I played with a Demo "PLUS" (4.0 Sr. #1 doubles) last night. Lost in a third set tie breaker on Hard true. I lost a few points in quick exchanges (usually my strength) and shots into my body due to the length. All of a sudden I have a Huge serve (usually my weakness) but not volleying all that great. What about choking up on the handle to volley ? Thanks for any responses.
