Reshafted my R9 SuperTri yesterday. I bought a new R9 adaptor 0.335 and a graphite design pershing shaft. Really easy to install , butt trimmed the shaft to this same length as the stock shaft and even though this shaft is a few years old now, I really like it. It loads really well and I like the feel has on the downswing. This was a really fun project.
have some pics of your finished work?
