I can hit my forehand pretty good and doing well with the 1hbh ever since i switched from the 2 hander. My reflexes and hitting volleys are all right, not bad enough to affect my overall game. My worse enemy are the SERVES though. I keep hitting double faults with my kick serves. Are there any drills or vids that are REALLY good on flat serves, slice serves, and kick serves? My flat serves can get in 60% percent of the time but I have to sacrifice some of my power. If people wanted to know, I use the eastern backhand grip for my kick serve (I saw on vids that eastern backhand provides more kick), but thinking of switching to continental to get the feel of the serve without switching grips. I have a problem of getting more kick on my serves and making them consistent. I want to learn both topsin and twist serves. Lastly, slice is a new world for me. I don't know if I should pronate a lot on this serve. Also, speed is a problem for this serve. Since I am a lefty, I want to take advantage on the slice serve.
