I saw from the Formula 100 and Gold 99 reviews that you rated the Gold 99 at a slightly higher power level. I notice that for whatever reason, maybe its combination of a faster swing, more weight, or playing more confident & aggressively that some days I can take a lower powered players racket and hit balls just as fast or faster than with a higher powered tweener. Is this the case with the Gold 99 vs the Formula 100, or does the Gold 99 really have a more powerful response? Also could you very briefly compare the two frames? The Formula 100 is frame I feel pretty familiar with. Thanks!
