For you. With the USGA maxing out certain aspects, many times it will come down to numbers. Those being spin, launch, etc. If a driver gives you numbers closer to optimum launch, then you will see a distance increase...GUARANTEED! That is why it is so crucial in todays day and age to be fit for a golf club and not buy blindly based on brand or loyalty.
I feel like Gru from "Dispicable Me" right now. Lightbulb.
If the drivers have the same COR but the weighting internally are different, spin numbers should change which would affect performance.
