Just came back from Newks Tennis Academy(Great academy! Broke 100degrees, though), and I couldn't do anything on my serve. I've been playing for 8-9 months now, and I use a slice/flat first serve. Maybe around 70-80. My second serve is a very "consistant" kick serve. Most kids my level have never even SEEN a kick serve, so I feel I would usually have the advantage, but it's not like that at all. It's like it pops up with a little kick to the right and balls are pounded back at me. I've tried increasing my racquet-head speed by alot, but all that gives is more pace and a ball that bounces really high and barely misses the fence. I toss the ball maybe a foot to the left, and my front-back placement is very inconsistant. Sometimes it's above my head, sometimes into the court, and even behind me. Could it be my swing path? My toss? Footwork?
