hi, i have a problem with my forehand serve. my serves have been pretty decent most of the time. however, recently, im starting to have troubles with my forehand short serve. when i try to do a short serve, my serve almost ALWAYS hits the white tape at the top of the net. my friends who were watching counted for fun how many of my short serves hit the white tape. it was 32 times in one set (we played the old 15 pts). then try to serve higher u say? well i tried, needless to say. my serves then become high enough for a ready opponent to smash back at me. it goes around 45 cm above the net. any experienced player would be able to rush and smash that serve. what do i do? any ideas?
