Question for the builders here.

I’m reshafting a set of Maltby TS3 irons (6 through PW) from Modus 105 Stiff into Dynamic Gold 120 S300. Standard playing length. I’m also switching to a Golf Pride Tour Wrap Midsize grip, which is about 58 grams compared to a standard 50 gram Velvet.

I prefer a final swing weight around D2.5. My question is about the best way to have these built at Second Swing in Minneapolis.

Should the builder swing-weight the clubs using a lighter 50 gram grip as a placeholder and then install the midsize grip afterward? Or should they install the actual midsize grip and target D2.5 with that grip already on the club?

I don’t want the heavier grip to throw the final numbers off, but I also don’t want to overthink it if the right answer is simply “build to D2.5 with the real grip installed.”

For anyone who has done similar builds with DG 120 and midsize grips, what approach worked best?

We would dry fit the build with the components you were actually using. Hopefully the builder will know how to do this. If you are building them to standard playing lengths, there will probably need to be some weight added to get tot he D2.5 with those components. Even though the shaft is heavier, the heavier grip will counterbalance a bit. At standard length my swing weight calculator is saying they will be around C8 with no weight added. Calculators are not always that accurate, but my guess is the will a little lighter than the D2.5 than you want.

The only way to dial it in is to take the time to dry fit each club and adjust the weight accordingly, using tip weights.

I would add that if you stayed with the 50 gram grip, you should get around C9.5 to D0 with no weights. Again, based on the calculator.

I don’t have the expertise to answer your question. But several people at Golfworks will answer your question.

Golfworks has a swingweight calculator. Which given the data you provided they can give you an answer.

I posted a similar question here and they answered it. The calculation came really close to the final swingweight.

The club builder you go to should dry fit the first few clubs just to see where the swing weight falls. The swingweight for epoxy and tape can be taken into account.
