EXACTLY my scenario. I'm a down striker divot taker like you. I started getting elbow and joint pain 10 years ago, and went from X100's to the 6.5 Pxi shaft. Still stout, but not quite as stout feeling as the reg Px, and it helped with the pain ...but the pain would still flare up at times. Particularly after hitting a bucket off the mats. I went to the MMT 125tx, and I've never had another flare up. I have limited my hitting off mats like before though. Mats are like hitting off concrete, and a joint killer. What I find odd about the 125tx is it feels rigid, but doesn't swing rigid. If I take an X100 and flex it, it bends. The MMT won't. It feels like a telephone pole. But it somehow kicks just right and feels smooth.
