GolfWRX Spotted: Cobra RF Prototype irons



Cobra Golf tour staff members have always had some of the coolest irons in the game. From Bryson’s first single length sets to Rickie’s first black forged CBs—being part of a smaller staff means attention to detail for each player, and in the case of Cobra and Rickie Fowler, that means truly one-off prototypes!

Yesterday, we got a sneak peak when someone at the Floridian Club posted a distance shot of Rickie’s clubs on the back of a cart. Although it was from a distance, an astute eyes quickly noticed that these were not a current model iron and speculation started to swirl.

Starting early this morning photos starting making the rounds on social media after they were initially posted in the GolfWRX Forums by Member J13, featuring what looks to be close up in-hand images of Rickie Fowler Cobra Prototype blades. The telltale signs include Rickie’s signature Tungsten toe weight to help increase head weight in each head, and the obvious RF initials milled into the toe, under a King Cobra Crown.

Although the pictures are now out, we have few details to go on from Cobra. What I do know is at the Cobra SpeedZone event hosted a few weeks ago to showcase the new line, there was lots of hush-hush discussion that we might see something new coming in the better players category soon, but no pictures or other details were released. These pictures certainly indicate that the Cobra iron team has been working on something with Rickie, and gotten them to the point of having them out in the world for testing.

This is merely speculation, but what’s interesting to point out is that nowhere in the iron does it say forged! Could this be because it’s still a prototype and they didn’t want to go the extra step to stamp that on the head or could it mean something else?

The picture above shows the head on a fixed block—something observed during the CNC milling process, but going deeper Cobra has been pushing the limit of iron construction for a long time, and last year did they introduce a (MIM) Metal Injection Molded wedge to the consumer. Could this non-forged blade be the result of using MIM technology to form a mostly finished iron head to then have the face milled?

Like I said, we don’t have any confirmation yet from Cobra and their R&D team, but this could be a very interesting development for full release iron construction come 2020.

    These look fantastic. A lot like the new Titleist 620 MB. It seems like the blade length is a little longer than some blades, which I like, but it also looks like they have a pretty sharp leading edge and no camber, which would worry me. But granted, it’s hard to get a definitive look from these pics alone.

    Are you on the Cobra payroll? How many articles can you write about Cobra? Enough already.

      When new product gets released, it’s standard procedure to write about it. Don’t you think? Don’t be so triggered, guy!

        Trendy new term I am seeing everywhere…’triggered’. People who use the term are so ‘with it’. I am guessing that they are the same guys who used to say ‘zombie thread’ or ‘use the search feature’.

    I’ll get ’em if the price is right. (say… $750)

    I knew there was a reason why ive been sandbagging on replacing my 2017 Cobra MBs. I have a set of the OG TW Nike blades and a set of Mizunos that pretty much just sit around bc the Cobras are that much better.

    Gorgeous looking blades, such a good looking port for the tungsten weight to create COG, hope that they come in Lefty!

    With these blades, all I need is a basket of bread and sliced butter! Let’s eat, and add 15 strokes to my scorecard!

      It’s hard not to disagree with these comments
      They are beautiful, but they are mean, very mean, they make the MP20’s look like GI’s…

      Like most amateurs, I’d imagine your poor rounds are caused by hitting drives ob, chunking chips, and 3 putts. I’ve played everything from blades to SGI’s and my scores never change based on the irons I’m carrying.

      • Jack

        Nov 26, 2019 at 9:01 pm

        Ain’t that the truth. Just play what you like. Nobody has actually quantified how many strokes you lose playing SGI vs blades. Of course, if you have a really slow swing speed and have trouble getting the ball in the air, you should be the SGI since even a good strike will not yield a good shot. But for average speed guys it should be OK.

        Nov 27, 2019 at 4:14 am

        I can’t disagree with you, if I keep it in play I score well, very well
        Currently swapping in/out P750’s and MP18’s, and the best irons I ever had were 710MB’s
        Not afraid of blades and never played any type of GI club, but these new Cobra’s remind me of my first set of irons that belonged to my father, a set of Wilson Staff blades….now those gave many a stingy finger

Top 10 clubs of 2003—inspired by Adam Scott’s Titleist 680 irons



As has been well documented, Adam Scott recently won the Genesis Invitational with a set of Titleist 680 blade irons, a design that was originally released in 2003. One of the great benefits of being one of the best players in the world is you don’t need to search eBay to find your preferred set of 17-year-old irons. Titleist has been stocking sets for Mr. Scott—even to the point of doing a limited production run in 2018 where they then released 400 sets for sale to the general public.

A lot of time has passed since 2003, and considering the classic nature of Scott’s Titleist 680, I figured now was a good time to look back at some other iconic clubs released around the same time.

Ping G2 driver

This was Ping’s first 460cc driver with a full shift into titanium head design. The previous Si3 models still utilized the TPU adjustable hosel, and this was considered a big step forward for the Phoenix-based OEM. The driver was a big hit both on tour and at retail—as was the rest of the G2 line that included irons.

TaylorMade RAC LT (first gen) irons

The RAC LTs helped position TaylorMade back among the leaders in the better players iron category. The entire RAC (Relative Amplitude Coefficient) line was built around creating great feeling products that also provided the right amount of forgiveness for the target player. It also included an over-sized iron too. The RAC LT went on to have a second-generation version, but the original LTs are worthy of “classic” status.

TaylorMade R580 XD driver

Honestly, how could we not mention the TaylorMade R580 XD driver? TM took some of the most popular drivers in golf, the R500 series and added extra distance (XD). OK, that might be an oversimplification of what the XD series offered, but with improved shape, increased ball speed outside of the sweet spot, and lower spin, it’s no wonder you can still find these drivers in the bags of golfers at courses and driving ranges everywhere.

Titleist 680MB irons

The great thing about blades is that beyond changing sole designs and shifting the center of gravity, the basic design for a one-piece forged head hasn’t changed that much. For Adam Scott, the 680s are the perfect blend of compact shape, higher CG, and sole profile.

Titleist 983K, E drivers

If you were a “Titleist player,” you had one of these drivers! As one of the last companies to move into the 460cc category, the 983s offered a classic pear shape in a smaller profile. It was so good and so popular, it was considered the benchmark for Titleist drivers for close to the next decade.

Cleveland Launcher 330 driver

It wasn’t that long ago that OEMs were just trying to push driver head size over 300cc, and Cleveland’s first big entry into the category was the Launcher Titanium 330 driver. It didn’t live a long life, but the Launcher 330 was the grandaddy to the Launcher 400, 460, and eventually, the Launcher COMP, which is another club on this list that many golfers will still have fond memories about.

Mizuno MP 33 irons

Although released in the fall of 2002, the Mizuno MP 33 still makes the list because of its staying power. Much like the Titleist 680, this curved muscle blade was a favorite to many tour players, including future world No. 1 Luke Donald. The MP 33 stayed in Mizuno’s lineup for more than four years and was still available for custom orders years after that. Unfortunately, if you are looking for a set now you are going to have to go the used route.

Callaway X-16 irons

The Steelhead X-16 was a big hit at retail for Callaway. It offered greater forgiveness than the previous X-14’s but had a more compact shape with a wider topline to inspire confidence. They featured Callaway’s “Notch” weighting system that moved more mass to the perimeter of the head for higher MOI and improved feel. There was a reduced offset pro series version of the iron, but the X-16 was the one more players gravitated towards. This is another game improvement club for that era that can still be found in a lot of golf bags.

Ben Hogan CFT irons

The Hogan CFTs were at the forefront of multi-material iron technology in 2003. CFT stood for Compression Forged Titanium and allowed engineers to push more mass to the perimeter of the head to boost MOI by using a thin titanium face insert. They had what would be considered stronger lofts at the time sounded really powerful thanks to the thin face insert. If you are looking for a value set of used irons, this is still a great place to start.

King Cobra SZ driver

In 2003, Rickie Fowler was only 15 years old and Cobra was still living under the Acushnet umbrella as Titleist’s game improvement little brother. The Cobra SZ (Sweet Zone, NOT 2020 Speed Zone) was offered in a couple of head sizes to appeal to different players. The thing I will always remember about the original King Cobra SZ is that it came in an offset version to help golfers who generally slice the ball—a design trait that we still see around today.

Today from the Forums: “The importance of wedge fitting”



Today from the Forums we delve into a subject dedicated to wedge fitting. Liquid_A_45 wants to know if wedge fitting is as essential for golfers as iron fitting, and our members weigh into the discussion saying why they feel it is just as imperative.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • Z1ggy16: “Super important if you’re a serious golfer. Even better if you can get fit outdoors on real grass and even go into a bunker.”
  • ThunderBuzzworth: “The biggest part of wedge fitting is yardage gapping and sole grinds. If you have a grind that doesn’t interact with the turf in your favor, it can be nightmarish around the greens. When hitting them try a variety of short game shots with different face angles etc. with the different grinds to see which one works best for what you need.”
  • Hawkeye77: “Wedge fitting I had was extremely beneficial when I got my SM6s a few years ago. Mostly for working with the different grinds and how they interacted with my swing and on different shots and having an eye on my swing to help with the process and evaluate the results. My ideas of what grinds were right for me based on researching on Titleist, etc. just were not correct in 2/3 of the wedges I ended up with as far as the grinds were concerned. Good to have an experienced fitter available to answer questions, control variables, etc.”
  • cgasucks: “The better you get at this game, the more important wedges are.”

Today from the Forums: “Pull cart recommendations?”



Today from the Forums we take a look at pull carts currently on the market. Bogeygolfer55 is looking for a quality pull cart for less than $300, and our members have been giving their recommendations in our forums – with Clicgear proving to be a popular option.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • Yuck: “I have had a clicgear 3.5 for nearly four years now. Holding up well with well over 200 rounds on it so far.”
  • Hawkeye77: “I had a Clicgear and liked it a lot, but my daughter “appropriated” it. Came upon an article a year ago about the Blade IP. Ordered one. It folds flat instead of into a cube which I like, and when I take it out it is quicker to get ready to go, and easier to take down. That doesn’t mean the Clicgear was particularly difficult, but it was more involved and 4 pounds heavier – don’t mind pushing a lot less weight.”
  • Celebros: “Another vote for Clicgear. The 4.0 just came out, so you may be able to find some of the 3.5+ models discounted soon.”
  • I_HATE_SNOW: “Sun Mountain user. Tall thin tires roll through the grass the easiest. Ours are old enough that the tires inflated. Once slimed, they stay up all winter. Mesh baskets on the cart are nice for carrying headcovers, water bottles, dog leash, etc.”
  • birddog903: “I’ve had a caddytek lite three-wheel version for a year or so. No complaints and I paid less than $100.”
