Without performing an exhaustive search on "kick serve" and reading through tons of threads, I figured I would start my own. Hope nobody minds. I really feel like I need a reliable topspin or kick serve as a 2nd serve if I ever plan on making that jump to 4.0 whenever it happens. I know I need to bend my knees and get low instead of arching my back, and my ball toss needs to be behind my head and to the left. Do you hit the ball as it's going up, or coming back down? I can sometimes get the ball to kick to the right when I'm serving to the ad side, but the spin is very subtle, and I would like to get that vicious spin that my opponent will have trouble getting his backhand on. Any tips?
