I am looking to replace the OEM shaft in my Ping K15 driver (12* loft). My swing speed is between 85 and 90 mph. I am looking for a couple of choices that would give me maximum distance off the tee. I am a “hitter” rather than a “swinger.” I know the OEM shaft has a .350 tip, but any shaft with a .335 tip is OK, because I have shims to make up the difference. Any suggestions? Thanks much!
