Just curious of what shaft flex you older golfers use. I am 68 and have gone from using a stiff steel shaft in my irons to a light or senior graphite shaft in my irons and from a regular shaft in my driver, hybrids and 3W to a light of senior shaft. I recently went through a pro fitter using trackman and found that with the change for my swing speed, tempo and other factors I increased distance in my 7 iron around 15 yards and my driver 20 - 25 yards.
