^^^^ this is good advice. Usually Serve is the last thing to click into place with a new stick. You don't want to mess everything else up at the expense of your serve....BUT...you can't win by double faulting too much, so you gotta get that serve in. I suspect Gads may be correct in thinking you are coming through quicker than normal and thus hitting serves into the net. Also, work at really pushing UP and OUT on your serves and it will give you higher net clearance.
