I used the rubberized 10 gram weights on a set of TS-2 irons. And of course theyre way to heavy. I can remove the larger piece of weight stuck in the head by heating the head; the lead just drops out – but removing the remainder of the weight from inside the graphite shaft is really tough. It’s rubberized as we know and drilling isn’t very effective. I’m tempted to 1) leave the piece of weight in the shaft. or 2) try again with another Maltby shaft. Sheesh what a job. Any tips – and thanks in advance.
