I have a pretty good forehand drop shot. I played this one point where i hit a backhand drop shot off a high, mid-court ball and my oppenent got to it. I hit a lob and pushed him back, then at the last second on the short ball, I played a drop shot and he didn't even move!!
I disguise my forehand drop really well, and since I play High School tennis when people pitty-pat their second serve over instead of ripping the return(which is what I usually do), I'll play a short angled drop shot usually for a winner. I do that once in ever other match!!
The drop shot is fun to play when you can use it right, huh?
