Photos of Cobra prototype irons made for Bryson DeChambeau
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.
See what GolfWRX members are saying about the irons here.

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.
Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

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

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.

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.

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

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

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…

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.
