    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?

      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.

      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?

      The secret is in the skrews… sooo goood

    • Knudson

      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.

    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.

      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… 😮

    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.

Bettinardi signs Eddie Pepperell



Eddie Pepperell is a singular quantity in to world of golf, so it’s not surprising that the Englishman has taken a unique route to becoming a Bettinardi staffer.

20 months ago, the two-time European Tour winner walked into Core Golf in Thame, Oxfordshire, and bought four putters, including a Bettinardi Studio Stock No. 8.

Pepperell, who jumped from No. 513 to No. 38 in the OWGR since putting the Bettinardi in play in April 2017, won’t have to pay for his putters any more. He joins the likes Francesco Molinari, Haotong Li, and Matt Kuchar as a Bettinardi staffer, the company announced the today.

“I’ve tried a number of putters and time and again, it’s the one model I keep coming back to.” said Eddie. “Positively I won’t have to buy a Bettinardi putter again, but having bought four putters from Core Golf I’m just hoping I haven’t put them of business as a result!” he added.

It was after Pepperell’s British Masters triumph in October that negotiations to bring him on board began in earnest.

“Once Eddie stayed ahead of a strong field at the British Masters to win his second Tour title of the year with a Bettinardi putter, we decided to reopen negotiations and we’re delighted with the outcome. It means that we now have another top 50 player in the world playing Bettinardi putters…” said Executive Vice President, Sam Bettinardi.

Here are the specs for his Studio Stock No. 8, courtesy of Bettinardi, which also provided the photos below of Pepperell’s putter (pre rust).

Material: Mild Carbon Steel
Finish: Mercury Gray PVD Finish
Face Milling: F.I.T. Face
Weight: 358 grams
Length: 33.25”
Lie: 71 degrees
Loft: 3 degrees
