I would like to use the Pro 125 Stepless or Pro 115 Stepless in an iron set but would like to have an R+ Flex. I understand they both may be soft to flex. What would you recommend to achieve an R+ Flex with either of these shafts?
Personally, I’d use the Pro 115 reg flex and hard step it once. Not an expensive proceedure, so build one club and try it.
