Do oversized club heads need stiffer shafts?
Yes, I know all about swing speed and going to be fit at Golfsmith, ect., ect. This is a general question. Basic physics would indicate that a club swung at the same speed using a larger high MOI club head (e.g. 460cc) would tend to flex a shaft more than a smaller club (e.g. 300-360cc) head with less MOI. Therefore, should we all be considering head size/MOI to shaft flex to swing speed interactions before we settle on a particular flex?
MOI is a measure of resistance at impact, not related directly to shaft flex, because it occurs after the shafts' initial flex. Shaft flex is affected by three things, weight and speed and internal resistance (torque). MOI in a shaft is (for most practical means) measured as torque.
A larger head does not guarantee a higher MOI, though it is likely. That being said, if possible, the highest MOI available should be an even larger consideration than flex. So to answer the question, yes and no.
