My question is this. I purchased a used set of 704cb from 3ball.com w/"A" flex Nippon shafts last fall, because I wanted to try "A" flex, but choosing CB & not 716 was probably a mistake. Several years I suffered a serious fall which left 5 shoulder operations, & much rehab. Now ready to buy a new set of AP1-716, not sure about "A" flex. Web site shows 950GH or TT XP-90, reading I assume that the Nippon shaft might have a higher trajectory than the TT, & the Nippon shaft might be a little "softer", am I right? What is available in "A" flex steel, I do not want graphite in my irons. Thank You, Dan Borchers
