How big of a difference is it. I'm a 5.0 player and have love using the 95 all during high school. I'm about to start my sophomore year at college and I want to try out for the tennis team this year. I've been thinking of switching from the 95 to the 85. How big of a difference does it make. I'm kinda short 5' 6", so does the 85 have less pop when it comes to serving?
