I used the TW tool to customize my PS100. Went from stock to 11.6oz and 325 swingweight. So added approx .8-1 oz (10,2 and handle) and about 18-20 swingweight pts. I like the results, but the frame is now just too powerful at my desired string tension (54lbs). I know I could increase tension to reign in control, but my tennis elbow gets cranky at higher tensions. Any way to get that heavier, more solid feel without significantly increasing power level? Hate to give up on these frames as I think I am close, jus cannot find the exact set-up yet.
