DonM I threw 24 gram weights from Hireko in my Ke4 Tours with Sk Fiber TT95 shafts and it has been awesome. Best I have hit irons in a long time. It did take a couple of range sessions. I put a 28 in my 3 wood and that feels good too. Not working great with a 64 gram driver shaft, but I am going to switch to a 76 gram shaft and make it slightly shorter and see how that works. In never really get along with 60-65 gram shafts. I still have to do my wedges. Strangely, 80-100 in the putter doesn’t work for me. Been trying 40 and 60 weights. The putter is Tour Lock so I can change while I am at the putting green.
