I almost always play on a hard court, though there are several fake-grass courts where I play. This is astroturf with sand on top. I played clay once but I really didn't like it. It was too slippery imo. I enjoy how fast the games on hard courts are. I recently had my racket re-strung after two years of having it. It was AMAZING how much faster and more accurate my shots were after it. I also got new grips because I sweat a lot, -big help. I played with a friend the other day that played in High school and college and I was afraid he was going to beat me easily. I hung in there, but lost 4 to 6. -We only played one set. Point is, I'm getting better. It's so nice to have something to do that gives me exercise, scratches my competitive itch and allows me to progress in my abilities. I love it. How about you? What do you play on?
