i have been using the prestige mid for about 9 years now and i hit a fairly flat ball and like to win points fast. i think the i may need a new stick but i dont know. i can not get enough spin production of the ground with this stick. i cant swing it fast enough in an upwards direction to hang with high level play anymore. on serve i have insane spin because i have super fast swing speed on serve but my ground strokes lack speed. any advice on what to do.
