    Any update on the single length build and the catalyst shafts? Curious to hear your comments about tip trimming the parallel tip shafts as well.

    It would be interesting if you could get heavier screws to use on the long irons instead of lead tape. Would be more consistent than the tape and more secure.

    I will literally pay PXG or you to do this, Knudson. The game desperately needs more single length options.

    I am experimenting with single length irons and love the way I hit the long irons bu the problem I am having is hitting the short irons (GW-8) fat and I am thinking about trying a mixed set with variable length up to the 7 iron and then 7 iron length 6 and 5 irons. I have a set of TM P790 and i can order a P790 6 and 5 iron from TM at 7 iron length and lie angle but am wondering about weighting since they will come already assembled so not sure how to get the head weights the same. Can they be weighed with the shaft in the head?

    If you were to use project x .370 shafts, would you use 7 iron shafts for each club or use the 4-pw shafts all trimmed to 7 iron length?

    • Knudson

      Oct 30, 2018 at 8:14 am

      The Project X Catalyst shafts are .370 and I tip trimmed them all like a 4-PW set. You can use all 7 iron shafts, that is the other option. From what I have been told, stronger players will typically like the standard set all cut down to 7i length.

    Hey Knudson, can you publish a chart of a comparison of distance and trajectory of the single length vs traditional length? In theory, the potential for consistency in swing feel from iron to iron is incredibly appealing. But then you need to reset distances….in theory?

    It was a complete let down that you took the easy way out changing the head weights in the short irons, especially since this is the “GolfWRX Shop.” Not too many people have PXG as their backup irons.

      I am currently modifying a wedge that has no weight ports, so stay tuned for that.

      … and a set of bombing clubs …. boyaaah

    • Knudson

      Oct 29, 2018 at 7:37 am

      They are old Black Widow Torque cords. I bought a ton of them years ago and they go on all my projects, then swapped out if the club makes the rotation!

    Brian, how did the single length PXGs perform for you?

    • aga

      Oct 28, 2018 at 6:07 pm

      The secret is in the skrews… sooo goood

    • Knudson

      Oct 29, 2018 at 7:34 am

      I have got them on the course twice and overall pretty good. I think the 4+5 irons might need to be bent 1* strong, but the ball flight is pretty good and turf interaction seems unchanged.

    What are you gonna do with all the wrong sole angles? Grind them so they all sit flat and the same? Show us that part as you grind off the soles until some of the numbers get ground off.
    Idiot club builder this guy is.

    • JM

      Oct 28, 2018 at 2:32 am

      Why on earth would you need to grind the soles to change the lie angles? You can change the lies all by bending them. Looking at the standard specs to bend all to same angle as say the 7i (62.5*) the most you’d have to do is 1.5* (4i and GW) and less as you get closer to the 7i.

      • CaoNiMa

        Oct 28, 2018 at 3:34 am

        Build one and see for yourself

        • JM

          Nov 2, 2018 at 2:43 pm

          Changing lie angle is independent from loft angle. I’m not sure what’s hard to comprehend about this….

      • aga

        Oct 28, 2018 at 6:12 pm

        If you keep the sole angles per standard spec you must increase face loft when bending. Simple geometry…. so obvious….

        • JM

          Nov 2, 2018 at 2:58 pm

          Huh? He’s building a single length set so he needs to bend the lie angles to match his specs for the chosen length (in this case he’s going off a 37″ 7 iron). So, if his lie angle on the 4i is 61* he needs to bend the lie angle 1.5* up to match his other single length irons (at 62.5*). This is based off standard specs from PXG. There should be no change in loft unless he adjusted improperly.

          • youraway

            Jan 19, 2019 at 7:21 pm

            JM, just wondering, since he used a 7-iron as his standard and built the others from it, should all shafts be tip trimmed the same as the 7-iron and butt cut to exact lengths after the lies have been adjusted? I thought we tip trimmed a shaft based on the desired length of the shaft. Normally tip trimming is much less for the 4 than a wedge, but if all shafts are same lengths, why gives?

    Thats awesome! I would love to try this out some day.

    Hey…. knucklehead knudson… I dare you to bend a PXG cast steel hosel by 2º without snapping the hosel… and kissing $600 byebye… 😮

    • JB

      Oct 28, 2018 at 9:20 am

      PXG’s are easy to bend. I have done it hundreds of times.

      • aga

        Oct 28, 2018 at 6:10 pm

        …. and hundreds of snapped hosels too …..?!!

    • BB

      Oct 28, 2018 at 9:33 am

      They are forged!

      • aga

        Oct 28, 2018 at 6:09 pm

        … only face forged… the body and hosel are cast steel.

        • AC

          Oct 29, 2018 at 3:53 pm

          I had mine bent, the builder said they are super easy to bend. Has bent a ton and not one lost. Are you speaking from experience or just “theoretically”?

          • JM

            Nov 2, 2018 at 3:02 pm

            If you read his other comments he’s clearly a troll. Either a PXG and/or SL iron hater. His feelings have grossly affected his objectivity.

    • Knudson

      Oct 29, 2018 at 7:44 am

      Knucklehead here. It is pretty easy to bend PXG irons, have done it numerous times. I went with a 63* lie angle, matching the irons I got fit for at the beginning of the year. Didn’t break a single iron, even going 2.5* on one.

      • aga

        Oct 29, 2018 at 7:46 pm

        In that case the PXGs will not retain their original lie angles after being beaten mercilessly by pro golfers… they will go ‘out of lie’… just like forged blades.

    Making bad into worse..!

    Bob’s lawyers will be drafting up the lawsuit shortly.

      How dare Knudson modify my beautiful best ever clubs… it’s criminal … :-O

    Tommy Armour offered this one length iron concept with their “EQL” model in about 1986….this is nothing different.Buy a set of used EQLs on eBay and save time and money ruining a traditional set.

    • JR

      Oct 27, 2018 at 3:35 pm

      totally totally uninformed comment

      • aga

        Oct 28, 2018 at 6:14 pm

        Yeah… PXGs are filled with magic prototype design magic… 😮

  16. Travis

    Oct 27, 2018 at 2:35 pm

    Pretty cool watch. Not sure why you’d want to do this to PXG’s but hey, to each their own.

    • Bob

      Oct 28, 2018 at 6:18 pm

      Knuckleheaded gearhesds who have no swing but want to own high status PXGs.

Forum Thread of the Day: “Masters fashion commentary”



Today’s Forum Thread of the Day comes from manku who opened the forum for a discussion on the best and worst of fashion exhibited at the 2019 Masters. Our members discuss the good, the bad and the ugly on show at last week’s opening major of the year, with some items, such as Adam Scott’s pleated pants, dividing opinion.

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.

  • alecfeltman: ” Adams pants worry me. Go back to the tailored slim version. He was dressing like a king until the masters. Rory looks great. Good fit and style. I’m a fan. I don’t understand the new cotton shirts from Nike. Jason Day on Thursday was odd, Friday he did good. TW – I’m a fan this week. I still don’t get why Patrick Reed is sponsored by Nike? That guy needs to wear some brand like Loudmouth. Koepka loves those crazy hats – I dig it. What is the connection between Nike “Snake Pack” and Augusta? I don’t see it. Can someone explain?”
  • elpadidji: “Went here after I saw Adam Scott, thought he looked super good. Got some Arnold Palmer vibes from him.”
  • hardcalier: “Kind of a bad week for fashion in my opinion. Adam Scott’s pants were super baggy like 3 out of 4 days. Tiger looked like he dusted off his wardrobe from 15 years ago. Fortunately, his game from 15 years ago came with it. Adidas stuff is pretty plain, never looks great but never looks awful either. Jason Day looks a little heavy in plaid. Koepka’s print hats were terrible.”
  • Yanki01: “Adam Scott who usually keeps it simple and clean looked hideous. Same for Jason Day and the yellow pants. Not sure if it was the old school look he was going for, but the AM shoes didn’t flow well. Some classic shoes maybe would have helped with some trimmed pants. Justin Thomas was best dressed and usually always is.”

Honma T World 747 Rose Proto MB irons are coming to retail



When Justin Rose signed with Honma in at the beginning of January, speculation ensued as to which irons the Englishman would play. Quickly, we learned Rose would game T World 747 Rose Proto MB irons — and he took to the clubs quickly, winning the Famers Insurance Open later that month.

So, clearly, the S20C mild steel irons work for Rose, as they’ve been in his bag since that point, but will they work for the general consumer? Up until this point, we’ve been unable to answer that question, as the irons were tour only. With today’s news, however, we now know Rose Proto irons are coming to retail.

According to the company, the irons, which are forged at Honma HQ in Sakata, Japan, are the result of several months of testing and modification in conjunction with Rose.

The world No. 2 had this say: “The idea of having a hand in the collaborative design process for my set of clubs was extremely exciting. Working with the Honma master craftsmen to create an iron that felt and looked great for me was one of the biggest thrills of my career.”

The irons feature varying CG throughout the set to achieve Rose’s preferred trajectories and a combination satin front and mirror back finish, as well as blended muscleback design.

Full specs below.

Rose Proto MB irons will sell for $175 USD per club and will come in a 4-10 iron set configuration. The company will also offer a 3-iron separately.

Spotted: Dustin Johnson with new Fujikura Ventus prototype at the Masters, RBC Heritage



Beyond the obvious big news of some guy named Mr. Woods winning his fifth green jacket this past weekend, there were some pretty interesting developments with another player that runs on a first name basis or at least initials: DJ switched drivers MID tournament and had a new Fujikura Ventus prototype shaft to go along with his new TaylorMade M6 as he took on Augusta National Saturday and Sunday.

We don’t have all the details yet, but from what we have heard so far this new Prototype Black Ventus is an even lower launching version of the blue Ventus currently available. If history is correct, and we are looking at a line extension, then the colors tell a lot of the story. The Atmos line features both a blue and black version with a final higher-launching red version to round out the series in what Fuji calls their color-coded launch system to make fitting and product recognition just that much easier.

Photos of the “black” prototype via Fujikura.

It’s not unusual for shaft companies like Fujikura to bring out prototype profiles utilizing technologies from their newest lines to try and get them into the bags of more players. Fuji’s newest technology is VeloCore, and we have already seen it adopted at a high rate. Here is some more info from Fujikura to explain the technology

“VeloCore is a multi-material core comprised of ultra-high modulus Pitch 70 Ton Carbon Fiber (about 150% stronger and more stable than T1100g) and 40 Ton bias layers that are the full length of the shaft for incredible stability. VeloCore Technology promotes consistent center-face impact and provides ultimate stability, tightening dispersion and increasing control. The result is a shaft that maximizes the MOI (moment of inertia) and ball speed of your clubhead through the reduction of twist during the swing and at impact, especially on off-center hits.”

This makes sense, considering any contact made beyond an absolutely perfect (almost impossible from a physics standpoint) strike in line with the COG of a driver head traveling at 120 mph will result in twisting at impact — MOI is maximized in driver heads to increase stability along with spin with Ventus and VelocCore, Fujikura thanks to their Enzo system, is better understanding how that relationship works with the shaft to produce new and better products.

Anyway, since we know DJ deviated from his traditional Fujikura Speeder Evolution II Tour Spec driver shaft for his weekend rounds this past weekend, we can expect to see it again this week at the RBC Heritage this week at Hilton Head, and we’ll have our eyes peeled to see where else this shaft pops up on tour.
