i would say that the level of my bh and fh are many levels above my serve. my groundstrokes have been solid lately but my serve is going no where. i've tried to learn from videos and my practicing hasn't seem to take me very far. any advice on where to start with serving? really in friendly matches, I end up just serving a "patti cake" serve to just get the ball in so my friend can slam it back on me. when i try to swing hard at the ball, I frame the ball badly. when i try to do a swing "correctly," my friend says I seem to slice the side of the ball so severely that it goes super slow and barely lands over the net. it's quite frustrating and i'm considering taking lessons and having the coach focus on serving. but before busting my wallet, I'd like to see if there's anything else I can try. After all, you guys have helped improve my backhand and forehand immensely!
