I’ve built a few iron sets where I need 8 gram tip weights. Most recently I’m building a set of PTM’s with UST DHI shafts. I largest tip weight I can find is 6 grams. The tip inside diameter is about 4mm. Does Golfworks offer a heavier tip weight? Is there another way besides lead tape. Currently I use the 6 gram weight and ram tungsten powder down the shaft. The rubber tungsten weights won’t fit, and are to costly for this particular build.
