Hey guys, Just wanted to get a few pointers on how to improve my serve.. All of my serves are flat and kick serves.. First serves are flat and seconds are all kick. I may hit a kicker from the ad court as a first serve occasionally. Heres the video: http://www.youtube.com/watch?v=XQAx5PmgeSM Every time I made a serve in I served from the other court (ad/deuce).. Double faulted once. Hitting with a nBlade 98... Strings about to snap. I'm thinking of changing racquets. Thanks!
