Hey everyone, what kind of shaft would you recommed for someone with a swing speed in the range of 85 to 95 mph. Just recently bought some Nike NDS with the uniflex shaft, I have now seen my distances decline. Used to be golden from 150 to 155 with 7 iron, now it seems that i struggle to get it there with 6. Is it true that the older aged golfer uses the more flexible shaft.....any recommendations would be great,thanks in advance
