Photos of Cobra prototype irons made for Bryson DeChambeau

Published

on

News came on Tuesday that amateur standout Bryson DeChambeau entered the 2016 RBC Heritage as a professional, and signed deals with Cobra-Puma (apparel/equipment) and Bridgestone (golf ball).

Although Cobra-Puma reported DeChambeau will play the RBC Heritage with his familiar Edel prototype irons, we spotted single-length Cobra King CB and MB prototype irons made for him, while live at the event.

We do not know if and when these irons will go into play, or if these are the same irons he reportedly played at the 2016 Georgia Cup. But check out more photos of the prototype Cobra irons below.

    No OEM will ever release a single length set. At best it will be a “custom option” if its ever offered.

    These are really interesting. In comparing these side by side with his Edel set, there is no external weight on these. Cobra’s R&D department must have done an exceptional job to get the weight into the head (probably the toe side) and making them look “normal”

    Reply to “lost in the convo”. I fabricated and play a set of “2 length” irons: 2 length because of difficulty with large weight adjustments required when using off the shelf iron heads. My 3,4,5,6 irons are 37 inches long and my 7,8,9,PW are 36 inches long. Love the simplicity – one swing and 2 different ball positions covers all irons; play much better.
    1. single length irons, and 2 length irons require lie adjustment assigning a lie to each club length. Note minimal lie adjustment (small changes) when using 2 lengths.
    2. The notion of loosing length with lon g irons is a myth propagated by those taking our $ for old style irons. I hit my 3 iron 195 and my PW 105 which is very similar to old style irons.
    The science (new term for golf clubs) is : at club-ball impact, MOMENTUM is conserved. Momentum – ( head mass) x (head velocity). Now, my 3 iron is 2 inches shorter than standard (about 5%) which costs 5% head velocity. BUT the club head is 21 g heavier which is 8.6% higher than old style heads. Thus, the momentum transfer to the ball – think ball velocity – actually increases with same length or 2 length irons. YOU DO NOT SACRIFICE DISTANCE OR SUFFER FROM SMALL DISTANCE INCREMENTS BETWEEN IRONS.
    As a bonus, the shorter clubs help you make solid strikes for added consistency and length.

      All the research I’ve ever done on this has always showed one thing in regards to length of club in irons. Since most irons use a .5″ increment that translates into less than 2 yard distance in length between clubs. So really if all the clubs were the same exact loft and one the length was different you would increase or decrease distance by 2 yards for every .5″ difference in length. Loft however; has a much higher difference in distance, which is why same length clubs with proper loft gaps works!

      As always though all the clubs have to be the same exact weight, head weight, shaft, grip, swing weight, and so forth for the same length shaft to actually work properly. This is also the reason why you can’t make a set unless you buy custom heads and shafts.

    I recently saw Ping Scottsdale’s selling for $299 in Torrance California at a shop called Golf Exchange.

    Does anyone know where I can find selling prices for a old Scottsdale PO box ping putter , I own one and want to see what it’s worth? Kushin model.

    I have a question about single-length irons. Does the offset have to be constant throughout, or should there be small changes in offset?

    • Scott

      Apr 13, 2016 at 3:16 pm

      Tom Wishon’s site has some good information on that. Tom has a set designed to be single length.

    • nathan

      Apr 13, 2016 at 5:04 pm

      All the clubs should have the same offset. Not sure why Tom’s set varies the offset from club to club.

      • Teaj

        Apr 13, 2016 at 6:40 pm

        +1 as I believe offset is to help with the squaring of the club of a longer moment.

    is the fact that the lie angle in his dingle length set is due his particular swing. For anyone else that is thinking of trying single length irons the lie angle doesn’t have to be so upright. I would think the biggest issue for anyone wanting to attempt single length irons would be the club head weights all the same and handling the yardage gaps. I think a lot of guys are sticking w/ tradition here and not even willing to try a set of single length clubs. Would be interested in trying if a company stepped up and did like the new Ben Hogan Golf irons and allowed a 30 day trial of a few clubs. Just my 2 cents.

      ‘Dingle length’ lol. I’m not sure if your asking actual questions, since your post of void of actual punctuation…but if you are actually asking, yes, weighting and distance falling is the challenge here. My buddy is going through the process of getting single length irons dialed in right now. The lie angle is unique to Dechambeau’s stance/swing. It’s VERY upright and he takes most of the angle out of his wrists at address, so his arms and the shaft are almost parallel. If your going the single length route, you’ll just have to have the lie angle measured for your swing, most likely not 13* upright.

          Lol. Not intentionally, it just makes it really difficult to discern if it’s a rhetorical question or for real asking. But sure, I’ll be ‘that guy’ in this instance.

    Yikes, not sure I could look down at a neck that is that rounded, Cobra may have to work on that a little, maybe get Miura to forge them with spin welded hosels and stamp cobra on them

    Wait a minute, they’ve been forcing this Einstein golfer dude and his crude scientific looking equipment down our throats for the past year and he jumps ship, to now hit traditional “looking” I know, I know already, they’re still one length, settle down, golf gear?! Sheesh, what’s next, he’s
    gonna switch to a baseball cap, or stop the presses, a visor? Or maybe white pants? Well Edel, he couldn’t win the Mahztaz with your gear, so now the musical clubs begin. You….uhhh….GO DECHAMBEAU, or however he spells his name.

    I still don’t know why edel made him a new set recently. Sad for them to put hard work and have to let him go.

    Those are some upright looking lie angles!

    interesting that it is blade low lofts and cavity high lofts. kinda backwards isnt it?

    • Greg Moore

      Apr 12, 2016 at 7:40 pm

      There is a full set of muscle back irons and a full set of cavity back irons. Not sure if he will put either one in play this week

      • Richard

        Apr 13, 2016 at 12:05 am

        Money talks, he will play a Cobra Iron before long even if it is not one of these two….and you can bet Cobra is biting at the bit to get it set so they can make a version for the public…I would think if your playing a one length set of irons you will have to be fit for lie angle for sure…

      • cody

        Apr 13, 2016 at 11:21 am

        thanks, it seemed so strange to me.

    • Teaj

      Apr 13, 2016 at 6:47 pm

      could be two sets. it could also be that the CB with the added weight to the lower lofted irons spins to much due to the added weight to the head to bring the swing weight up because of the shorter shaft length.

What Adam Scott said about his new 681.AS irons

Published

on

Adam Scott has used the same irons — Titleist Forged 680 — for the better part of 10 years.

“When you’re old and stubborn, you like what you like,” the 41-year-old told PGATOUR.COM.

Indeed, as he has transitioned into Titleist’s latest woods and wedges, the 14-time PGA TOUR winner has remained steadfast in playing his 2003 680 irons with KBS Tour 130 X shafts.

It was interesting, then, to see Scott with a different — but very similar — set of irons in the bag ahead of THE CJ CUP @ SUMMIT.

Adam Scott’s trust Titleist 680 8-iron

Scott’s new 681.AS Forged 8-iron

At a glance, the visually stunning irons look identically shaped to the 680s we’re used to seeing in Scott’s bag — similar large muscle pad on the rear of the club, similar hosel transition, similar generous amount of offset, similar topline. However, the irons looked substantially less worn and were stamped with 681.AS on the hosel.

What’s going on here?

Titleist declined to comment, but PGATOUR.COM caught up with Scott, who shared some details. As it turns out the new irons are the same…sort of.

Before digging into the 681.AS, we asked Scott why he doesn’t simply continue playing 680 irons, and when a set wears out, replace them with another. The answer, he said, was simple. Titleist “just ran out of original sets,” which the company stopped producing in 2005.

What to do? Scour eBay and used club stores? Frequent garage sales?

Scott indicated Titleist engineers took a different tack: They made CAD (computer-aided design) copies of his beloved 680s and CNC-machined what he called, “basically the same clubs.”

“Thanks to technology,” he said, “they’re as exact a replica as you can get, but with the way they’ve been made, I could argue it’s a more solid head with a more solid strike.

“I’ve been stuck on the 680s for a long time now,” he added. “…We’ve tried some stuff here and there. We tried bending the 620 MBs earlier this year, which I actually used at the Masters. I’ve been looking for 12 months for that new fresh set with good feel in the hands and good vibes, and we just couldn’t get there, so they took this project on.”

He continued: “It’s very nice for me that Titleist was able to do that. I know what I know. I’ve played it so long, I’m at a point where I think it’s detrimental to go searching and trying to change. I know how I play, and I know what I need to play well.”

Update: Titleist offered this statement, “This week at the PGA TOUR’s CJ CUP, Titleist Brand Ambassadors Justin Thomas and Adam Scott are each putting new sets of prototype Titleist muscle back irons in play. Feedback from the best players in the world is a cornerstone of the Titleist R&D process, and these prototype irons (621.JT and 681.AS) have been developed in collaboration with each player to better understand some key design variables such as shaping, sole design and CG placement – that ultimately may find their way into future Titleist iron development. We look forward to sharing additional updates on these prototypes as we gain feedback and learn more from each player’s experience.”
