question for LM Prestige (Mid) users i demoed this stick and was very impressed with it's control and feel. very solid and accurate ground strokes. toke me a while to get used to it's weight but once i got used to it my game improved a lot. but i had a big problem developing spin. ripping the ball was very difficult. i had to rely mostly on flatter strokes. is this mainly the raquet's character (heavy, small head, dense string pattern) or is it more of a stringing issue (i used head ultra tour-a polyester string, 56 ponuds). thanks!
