NO extra distance?

I haven't tested much but I figured you'd get about 10-15....no?

In theory, a center club hit on a 975D which has a COR of 0.830 vs. a center club hit on a current technology driver with the same COR, would yield the same distance assuming both clubs yielded the same launch conditions. The big advantage of the current technology is the forgiveness of the larger heads making your average drive longer and the ability to get better launch conditions from some shaft / head combos. The only reliable way to optimize those launch conditions by finding the right shaft / head combo for your swing is a driver fitting on a launch monitor or (rarely) a human equivalent. Well, you could also join the GEA and try every OEM shaft / head combo until you found the happy one, but that costs many greenbacks.
