Getting older, age 63, 6’1”, just lost 30 pounds, have some medical issues, and my club speed with a seven iron has decreased to 67 mph. Would the Fujikura Axiom shaft, 75 g, senior flex be too heavy for me? I have access to the irons I want with these shafts installed at a good price. I am around a 15 handicap. If you don’t think this shaft would work well for me, can you suggest ones that would? Thanks so much.
