I am thinking of soft stepping my KBS 80 regular shafts in my Taylor Made R9 irons from the 5 down to the 7 thru the set. Is there an issue reusing the shafts in this manner. I am older and have had back fusions, I think this would help. This is an effort to see how it would work out length wise and flex.
Thanks. I think I will try the double step down. The shafts are S300, so it will get them closer to a Reg flex.
