anyone tried the 11 to 4 "Rafter kicker"? i just saw this FYB new video with Rafter. i needed some new ideas for a safe & effective 1st, cause my flats % is low, and my serve generally hasn't got much speed. so i tried to improvise in mid match with this "11 to 5 sort of a kick serve". i probably didn't succeed much but still managed to put some different spin on the ball cause my opponent had at least 6-7 missed hits (totally out). for a first try i'm pleased anyone else using it?
