I would like to obtain a flex midway between a R and S flex for XP95 tapered shaft. For a 7-iron should I use a 6-iron or 5-iron XP95 S-flex tapered shaft? How many steps are there between R and S flex for the XP95 (2, 3, or 4)?
Probably looking at 2 steps. Check out Britt’s answer for a similar question recently: https://ralphmaltby.com/forum/question/does-soft-stepping-work/
