Okay, I have two different racquets with similar swingweights and balance which play completely differently when hitting my 1HBH. Racquet #1: My Head Microgel Radical Pro racquets are weighted to 12.1oz and are 6 pts head light. The headsize is 100sq in, and the stiffness/flex rating = 64. Racquet #2: My Slazenger Pro Braided racquets are weighted to 11.8oz, and are 5 pts head light. The head size is 95sq in, and the stiffness/flex rating = 73. A comparison from TWU is below: Both racquets have a similar open string pattern (Head is 16/19, Slaz is 16/18 ) but when hitting my 1HBH, the Slazenger has noticeably better plow-through. The twistweight of the Head is actually much better than the Slaz, so this has left me completely puzzled??? Is the difference that I'm noticing related to the smaller headsize of the Slazenger vs Head?
