I don't do math good...physics question.
Someone compute the math for me on this one. I'm back to experimenting with heavier weight shafts again. Overall, the heavier weight has been better for me in the back swing, a bad back has always been the issue. So I didn't do a breakdown when building test clubs (balance points, raw head weights, etc), so I just know the total weight differences (407g vs 434g) on the 6 irons. There might be a couple grams difference in head weight, but nothing more, and SW come out the same. Balance points between SF and DG, although not identical, are relatively the same. Results have me a bit puzzled. How much does shaft weight play into the total MOI of club and energy transfer potential? We all know the head weight does...but how much does the total weight/shaft weight play into it? I'm pretty sure it's a little more involved than the F=MA which is why I am asking for someone alot smart than me to solve. The interesting part of it is off-center hits seem to be noticably better on the DG vs my SF shafts...specifically toe side...which I find the most peculiar.
