Hey Britt,

I’m hoping to change shafts in my current irons. I currently game PXG gen5 0311 P 5-gw. I’m planning on buying Nippon Modus3 Pro’s in X flex from golf works.

I have 3 questions :

Since the Nippon shafts only go to “Wedge” Would I use two wedge shafts for my PW and Gap? Would I trim the gap shorter? or leave it the same length as my PW? If I cut it shorter how would that affect the flex?
Since the Modus comes in 0.355 and 0.370 is there a reason to use either specifically? My understanding is PXG clubs can accept both shafts but Nippon uses constant weight 0.370, so would that be the better route?
Do you have any suggestions for what I would need to do to get my swing weight to d2? Is there anyway you could help me understand how to do that? I’m planning on 0311p heads, Modus pro 120x, Golf pride MCC +4 midsize grips.

All I can really do is plug in say the #5 at 38.75″ with the components you are going to use and assume a standard head weight for a #5 iron 254 grams. So, with the shaft weight in the x flex at 120 grams, the grip weight as mentioned before is 66 grams, at the 3/4 inch over our standard length of 38″ being 38.75″, the swing weight calculator estimates a D2.1 swing weight. If you are adding 4 grams to the head weight, it would be D4.1. Not knowing the exact head weight progressions, and with your variable length progression, I really could not estimate what the final swing weight will be on the remainder of the set. Even with all that information, the calculator is only an estimator and it can be +- 1 or more from what the actual final build yields. I would suggest when building you dry fit all the components on each club and adjust what you need to get as consistent swing weight as possible. The length and length progression, the head weights and the other component weights will dictate what it’s going to be. Depending on the tolerances of all the components and the head weights, you may get +-2 within the set. Just can’t know until you get into the build.

First, yes, you would use two wedge shafts for the PW and the GW. How long you make them depends on your preference and the head weight. If they are the same head weight, then they could be the same length. That is what I do.

Second, We have that iron as using a .370 tip shaft, so yes, you can use either. Since Nippon makes both the .35 and .370 in discrete lengths, the only difference is the tip diameter. The weights are listed as the same. Some players prefer .355 because they say they like the feel better, but when both are the same weight and discrete lengths, my bet is 99% of players would not be able to tell the difference. There should be no difference in the playability.

As far as the swing weight, I would need to know the head weights and the playing length you plan to make them before I would be able to give a more accurate estimate. If I assume our standard length (38″ on a 5 iron) and the head weights are our standard, with the components you listed, the swing weight will be around C6-C7. So, you would need to add 10 to 12 grams of tip weights to get to a D2. The reason is the grip your using is heavy at 66 grams. If you used a 50 gram grip, the swing weight without any tip weighting would be around D0. Obviously if your playing length is longer than standard, then that helps and you would need less weight and maybe none depending on how long the playing length is.

Hey Britt, Thanks so much for your response.
I’m having trouble with the head weights as they are currently my gamers and have shafts still in.

At the moment my 7i is standard 37″ with accra i80 S flex shaft, the PXG head ordered +2 swing weights from factory, and a MCC +4 midsize grip. Yesterday tested at C8.5 at a fitting (unfortunately I don’t have access to that scale to swing weight the rest of my clubs)

I’m planning on going +0.5″ from standard in the set overall (38.75 5i, 37.5 7i). Using PXG’s standard cadance of 5/8″ steps to the 5 and 6i and then .5″ to the 8 and 9, then .25 to the P and G. (I struggle with the short length of my pw and gap)

I apologize for not including it in my initial message but my planned set is :
PXG 0311 Gen5 P 5-GW +2 weighted heads (so I assume +4g?)
Nippon Modus3 Pro Tour 120 X
Golf Pride MCC +4 Midsize. Unfortunately tour velvet midsize +4s are basically the same weight so no real way to cut weight there.

I really appreciate your help with this. Without the discrete head weights am I at an impasse?
