My brother in law is playing stiff steel in his irons and wants to go to a regular flex graphite.  Does the pro series in in R flex play stiff (I’ve heard they do).  If so he try the A flex in an iron?  He swings rather hard.  I also want to know if the same applies to UL driver shafts.  If I want a Senior flex will it play stiff (should I try the “L” flex instead).  I only hit my drives about 175 to 190 yards.

Thanks
