Bryson DeChambeau — winner of the 2015 U.S. Amateur and NCAA Men’s Individual Golf Championships and recently turned professional — plays with a unique set of irons and wedges that all measure the same length.

In my video, I review Sterling Irons from Tom Wishon and Jaacob Bowden that are designed to also measure one length throughout the set.

    Just tried two Pinhawks (20 and 25 degrees numbered #4 and #5) for two rounds now and like them very much so far. Cannot confirm the reported low ballflight. They behave like a regular #3 and #4 iron which corresponds to the loft. Still struggeling with the 20 degrees iron played from the fairway but the 25 degrees works already great! Hit it much more consistently compared to my regular #4 and even #5 iron. Cannot complain about the distance as well. The shafts are 36,5 inches (FST 115 stiff) and the lie is 63,5 degrees (one upright). I was not looking for a single length set but replacing the longer irons definately makes sense to me! 🙂

    Mark great review on tom wishons sterlings. I myself had a set of conventional irons build to SI. And they performed great the short irons were very accurate we did have a bit of adjusting to do with the 4&5 irons the trajectory was too low and it was loosing distance. We ended up increasing loft and now all is fine. Did notice though that on the 4&5 irons i did need to have at least 80mph swing speed.. Overall i really believe the concept works. Cheers

    The single length concept is fine. But just don’t understand why people (especially golfer) always try (and hope or beg) to find an instant cure to their swing.

    If you cannot handle the 4,5 or 6 iron, try the hybrids, they are much easier to hit and launch high and straight. Or just make the 4,5 and 6 have the same length. If you cannot take care of 7,8,9 and P, sorry, dude. You really need to work on your swing, seriously.

    Use the same length for 5-SW may sound intriguing for some people, but you still need to deal with the different lengths of your driver, fairway wood and hybrid. So why bothers?

    I guess 95% of people who would like to try the single length irons, have some challenges to hit the 4 and 5 or even the 6 iron. Just use the hybrids or hybrid-iron combo set (should be around $200-$300) rather than spending $1000 and look like a sucker.

      The single length concept is AWESOME! I (was) a 1 HCP and can hit the 3 and 4 irons as well. But i definitely hit the 7 iron much more solid then my 4 iron.
      i now playing a single length set and hit the 4 as solid as my 7, or 9, or P. I loosed 5 yards. So who cares about 5 yards if you hit them MUCH better? I also use a hybrid and a driver. So i have 3 lengths in my bag. And thats pretty easy to handle.
      Sure, this is not for every one. But it makes the game a lot easier. Droped to +HCP this season…and this looks definitely not like a sucker! The + on the scorecard looks SEXY 😉

        Would love to know more. I have been racking my brain on the single length concept. I’m a 3 handicap. There are 3 distinct versions and concepts of the single length out there with Cobra, Wishon and 1Iron Golf. How deep did you look into this and what advantages and disadvantages did you run into while trying to decide. I’m 5’7″ 8 iron 152 yds. thanks for your response

    Given the cost of Sterlings and lack of local demos, I may just build a set of PinHawks when they become available again. I have an unused set of TT Command shafts in the closet that need something to do. Not unhappy with my Speedblades, but just another curious engineer.

    I would like to see the results of a real round. The concept is very interesting, but for me, chipping and pitching with a 7 iron length wedge would be difficult. The idea makes sense, and it may be THE NEXT BIG THING.

    Few things:
    1) Shouldn’t the offset be constant throughout the set? According to the specs, the offset is not the same throughout the set unlike the Pinhawk irons.

    2) Mizuno’s current wedges are single length at 35.25 inches, so at least that is a good place to start in terms of single-lengthening the wedges.

    • Jaacob Bowden

      Jun 7, 2016 at 10:12 am

      Historically, the low-lofted irons in single length sets would fly too low and the high-lofted irons would fly too high. The progressive offset slightly helps address this by moving the center of gravity forward and backward from head to head. This combined with some other built-in features help achieve similar peak shots heights throughout the set.

    Great commentary. It is an excellent demonstration of the viability of SLI’s. Mark does mention the possible benefits of single length to the new/beginner several times with the caveat that he never had the adjustment problem. I like to see golf as a staged learning process with the objective being to make arriving at the earliest and highest possible competency level the main objective. This approach tends to move new golfers to become much more enthusiastic about the game rather than less. Single length clubs when combined with systematic instruction will likely increase beginner and new golfer competency. Only systematic, quantitative data can definitely prove this point and as we know this information does not exist.

    I would go sofar as to suggest that standard SLI’s could easily be regarded as the beginning golfers friend; and upon reaching the 10 handicap level, graduation could occur to either longer clubs or SLI’s which have had the heads tweaked to achieve higher performance. Serious golf enthusiast’s especially those in the single digit handicap category commonly forget that 98% of golfers will never achieve a single digit handicap.

    Definitely interesting but worth a closer look at the numbers. The short irons seem to work very well, they address the main issue single length (I’ve tried the Pinhawks) has had, by lowering the peak height to a fairly uniform level (making them less hot off the face), and getting the gapping correct.
    However, only 19 yards difference is covering the 5 – 7 irons, and the peak height of the 5 iron has dropped down to 26 yards from 30, without any more spin, which suggests the loss of a few mph due to the shorter shaft is reducing ball speed and compromising distance too much, I would think Crosssfield is realistically 10 yards down on a standard modern 5 iron.

      And that is what I’ve found as well. I’ve actually been tinkering with a 4-iron at 24, and then going to 6 at 29. Those pinhawks are 5º between all of them, but they don’t have the material differences. I’ve actually found that the long irons don’t get high enough, and that’s what causes gap crowding. This of course is based on my experience with “regular” heads. I think this really drives home the point that 8-iron and down is all about dialing in your distances, but some really do need that length at the top of the irons. My other set is 8i-58º within 1/8″ of an inch… all at D9. Then it’s standard 1/2″ steps. It isn’t as easy to hit, but the long iron problems don’t exist.

      Most second shots are within 150 yards, so all the better to get the 7/8iron and down the same.

      The 5 & 7 numbers are a bit skewed by a mishit 5 and a shot wit the 7 that was 5 yards longer than the other 2. Also, the 7 iron was the only one with a peak height of 30. I suspect a larger sample would normalize the distances.

    Totally makes sense. If you don’t need different lengths and lies to create the proper distance gaps, then why introduce those variables? I was always intrigued by the old Tommy Armour EQL irons. I predict these will sell Big and a create a wave of SLI players.

    This is hardly a fad. Moe Norman played SLI clubs and is one of the greatest golfers of all time. The truth is on the wall…SLI clubs can be very beneficial to anyone out there, just have to find a set.

    • kyle

      Jun 6, 2016 at 9:45 pm

      Moe didn’t use single length clubs during his actual playing career, just later on when he endorsed the natural golf stuff.

      That being said, SLI are probably a good option for some golfers.

    • es

      Jun 6, 2016 at 11:53 pm

      Moe Norman one of the greatest of all time? Maybe a great Canadian player or maybe a great ball striker… he could probably middle a 48inch 7 iron, not the ideal SLI user trying to find consistency…
      But SLI does have a great new ambassador – the Great in his own mind and future web.com player Bryson DeChambeau. Have not seen such celebration for a player yet to secure a PGA tour card with only 1 top 20 finish and 4 missed cuts in a row.

    SLI is a great concept. I’ve posted on here plenty of times that I think almost every golfer would be better suited by a 1/4″ gapping or SLI. The hard part is that the lofts and ball apex get a bit funky when you take standard clubs and make them SLI. I think the hardest part about transitioning to SLI isn’t the equipment; it’s the mentality that irons are for exact distances, and not following the “distance iron” marketing. When you see guys hit their 6 iron 210 on the PGA, you get guys who want that same thing, and you end up with loft-jacking. If you can shed all of that baggage, and embrace that your irons are intended to get you an exact distance, things get better very quickly.

    • Jim

      Jun 6, 2016 at 7:49 pm

      Totally agree. I would think that 3/8″ would be far better than 1/2″ as well. I’m currently working to setup clubs using 1/4″ increments because the clubs will be far more consistent up and down the set.

Callaway launches Rogue, Rogue Pro and Rogue X irons and hybrids

Published

on

With its new line of Rogue irons — consisting of Rogue, Rogue Pro and Rogue X models — Callaway continues its search to answer a conundrum that’s plagued game-improvement irons for years; how do you make an iron that produces great ball speed without sacrificing sound and feel. The dilemma is that in order to increase ball speeds, engineers must make the faces of the irons thinner. The problem is, the thinner they make the faces, the more vibration is caused at impact, creating a longer-lasting, higher-pitched sound. Very few golfers want that off-putting, clicky sound, but they do want the ball speed and distance.

So, that’s why companies are experimenting with different materials and injections between the faces of game-improvement irons and their bodies. That buffer creates a dampening effect to reduce vibration, while still allowing faces to be constructed thinner to raise COR (coefficient of restitution, a measure of energy transfer) and ball speed. Companies such as PXG irons use TPE injections, and TaylorMade uses SpeedFoam in its new P-790 irons; Callaway says those constructions either constrict speed, or they don’t have a profound enough effect on vibrations.

For its Rogue irons that are made from 17-4 stainless steel, Callaway is using what it calls urethane microspheres, which are essentially little balls of urethane that it combines together, in the cavities of its irons. The difference between these spheres and other foams and materials on the market, according to Callaway, is that the material is porous. Callaway says the microspheres work to dampen sound without negatively effecting ball speed.

The inner material in the cavity works in tandem with familiar technologies from previous iron releases such as Apex, Epic and Steelhead XR. Callaway says it has improved upon its VFT (variable face thickness) and Face Cup technologies, focusing on thinning out portions of the face where golfers tend to miss shots — low on the face, on the heel and on the toe. Each of the Rogue irons also uses Internal Standing Wave by way of Tungsten-infused weights that help control the center of gravity (CG) in the club heads; that means centering the overall weight between the scoring lines, and controlling where the CG is placed vertically throughout a given set (re: higher on the short irons for more control and spin, and lower on the long irons for more height).

For the consumer, all of this means getting performance-driven irons at a lower price compared to the Epic and Epic Pro irons. Each of the irons will be available for pre-sale on January 19, and come to retail on February 9. Read on for more info on each of the specific irons, and the Rogue and Rogue X hybrids that introduce Callaway’s Jailbreak technology into hybrids for the first time.

Discussion: See what GolfWRX members are saying about the Rogue irons and hybrids in our forums.

Rogue irons ($899.99 steel, $999.99 graphite)

Callaway’s Rogue irons are the standard model in this line of irons, equipped with all of the technologies described above. According to Callaway, these are essentially Steelhead XR replacements, but have more compact shapes. In the Steelhead XR irons, Callaway used a wider profile in order to center CG between the scoring lines, but due to the inclusion of the Tungsten-infused weights in the Rogue irons, it was able to shape the irons more similar to XR and X-Hot irons of the past — more preferable shapes for GI irons, according to Callaway.

Stock shafts include True Temper’s XP105 steel shaft, and Aldila’s Synergy graphite shaft.

Rogue Pro irons ($999.99)

The Rogue Pro irons, as you may expect, have a more compact shape, thinner toplines and thinner soles than their standard-model-counterparts. Therefore, the Pro design will yield more control that better players will prefer, but they are still packed with all of the performance-enhancing technologies of the Rogue irons. They also have a chrome plating that better players may be drawn to.

Rogue X irons ($899.99 steel, $999.99 graphite)

Callaway described the Rogue X irons to me as “bomber irons.” They have lofts that are 3-to-4 degrees stronger than the standard Rogue irons, and they have longer lengths and lighter overall weights, but according to Callaway, they will still launch in the same window iron-for-iron (re: a 7-iron will launch like a 7-iron). Despite cranking down the lofts, they have bigger profiles, wider soles and more offset; those designs work to drag CG rearward, which helps to increase launch.

Combine that design with the Rogue’s VFT, Face Cups, Internal Standing Wave and urethane microspheres, and the result is an iron that’s “all about distance,” according to Callaway.

Rogue and Rogue X hybrids ($249.99 apiece)

As noted previously, the Rogue and Rogue X hybrids include Callaway’s Jailbreak technology. Like Callaway’s Rogue fairway woods, they use stainless steel bars behind the face instead of the titanium bars that are used in the Rogue drivers. Also, like all of the other Callaway clubs that use Jailbreak, the idea of the design is that two parallel bars inside the club head connect the sole with crown help to add strength to the body at impact, allowing the faces to be constructed thinner, thus, create more ball speed across the face. The Rogue and Rogue X hybrids also have Callaway’s familiar Face Cup technology.

The standard Rogue goes up to a 6-hybrid, while the oversized, Rogue X “super hybrid” goes up to an 8-hybrid. Similar to the Rogue X irons, the Rogue X hybrids have an oversized construction, a lighter overall weight, and longer lengths. The goal with these Rogue X hybrids is to create higher launching, more forgiving and longer hybrid options for golfers who need help getting the ball in the air.

First Look: Precision Pro NX7 Shot laser rangefinder, made for golfers and hunters

Published

on

Precision Pro’s new NX7 Shot is useful whether you’re hunting birds or birdies.

In just over 3 years, Precision Pro has become a player in the laser rangefinder market, quickly developing a reputation for products with maximum features at a price that’s lower than comparable offerings from competitors. Precision Pro came out with its NX7 Pro in 2017, and is following up that offering with the new NX7 Shot, which is designed to hit the two biggest markets for laser rangefinders: golfers and hunters. That’s probably why the company put a camouflage design on the water-resistant and shockproof body of the NX7 Shot.

Inside, the rangefinder has target acquisition that is meant to stabilize even when shaky hands or windy conditions are in play. The NX7 Shot also has an effective scanning distance of 400 yards, which is more than adequate range for golfers not named Dustin Johnson. Other features of the NX7 Shot include is its Scanning Mode, which allows the user to pick up multiple targets in one motion, and its Last Priority Mode, which lets the user acquire a target through tree branches and cover.

The NX7 Shot also comes with a 2-year warranty and free battery replacement for the life of the product. Regarding the warranty, Precision Pro Co-founder Jonah Mytro says “it’s something that nobody else in the industry is doing” and it “shows that we value our customers and that we want them to keep using our products for life.”

It’s designed to be legal for competitions that allow rangefinders, and is listed at $249 with free shipping when ordered from the Precision Pro website.

Snell adds MTB Black and MTB Red to lineup, thanks in part to GolfWRX forum feedback

Published

on

Snell Golf entered the market in 2015 when Dean Snell, co-creator of the Titleist Pro V1 and TaylorMade Penta, decided to sell premium golf balls direct to consumer at a fraction of the standard premium golf ball price. With massive year-over-year growth, the company’s offerings have been well received by the golfing public.

Snell is expanding its MTB line with the release of the MTB Black and MTB Red models. The company indicates the Black and Red models leveraged customer feedback to expand an already successful line.

“Through evaluation of customer feedback, we are able to go through the design and testing process with a clear understanding of what the customer wants to see and feel in their Golf Ball. Pair our expertise and experience with customer suggestion and the result is a ‘Tour Like Experience’ with extra cash in your wallet for a round at the bar,” says Snell Golf founder, Dean Snell.

We asked Snell about the feedback process, and he had some interesting (and flattering) things to say.

“One of the biggest parts of the feedback came from the forums at GolfWRX. I check it weekly for sure, sometimes every other day. There’s one [thread] that started when we started and it’s still going…the information, with people playing and testing, I typically read that.

“And then I get a lot of emails. I read them all, and then I make a big chart, and I fill it in…”high spin,” “low spin,” etc. Then I read and mark the boxes with what people are saying, and when a box fills up, that’s a voice…So there were three big voices from consumers, and that led to these balls.”

Snell said when he worked at Titleist and TaylorMade, tour pro feedback was paramount. Now that he’s offering a direct-to-consumer product, however, the consumers are his “tour players.”

This is a different approach [working with consumers] and asking, “What do you want?” You can’t satisfy everything, but when you hear a strong voice over and over, that’s what we take into consideration.

MTB Black

  • 3-piece thermocast urethane cover golf ball with a 360 dimple pattern
  • Seven percent lower compression core than the original MTB
  • Softer core lowers spin with the driver

Snell says: “Driver spin: anytime you can lower it, it’s going to make the ball better. We keep the same performance [as MTB]…it’ll just be a touch longer.”

MTB Red

  • 4-piece thermocast urethane cover golf ball with a 338 dimple pattern
  • Dual Feel Technology: Provides a firmer, more responsive feel on driver and long irons shorts, while continuing a very soft feel on short irons and around the green with more spin as well
  • Available in Optic Yellow in addition to White

Snell says: “The MTB Red became a four-piece ball. We had to add an inside layer–an inner mantle–to add spin to approach shots. You control the spin rates through the set with the layers of the ball. Getting that fourth layer in there really works for the approach shot control and spin. Otherwise, to add spin, you’d have to raise the core [compression], but when you do that, you make the driver shorter. And the “yellow tour ball” market isn’t big, but the voice in our group was loud.”

Both golf balls will be offered at a retail price of $31.99 per dozen, and are also available in a Value Pack of 6 dozen for $163.99 ($27.33 per dozen).

New models are available at SnellGolf.com for pre-order. Shipments are scheduled for February.
