Recently started playing the M-fil 200 again, not really used this racket that much. The swingweight if I remember is about 340. The power level is higher than I expected, it's not that immediately powerful, but when you get the weight moving a bit there really is a lot of power. This is no problem on serves and volleys, but on my groundstrokes I find the ball getting away from me more than I want, couple this with the tight string pattern and you really need a clean hit. Ive always had a big serve and with this racket its bigger than ever. Must be the swingweight?
