I currently have the Fischer M Speed Pro 1 as a demo. The racquet feels great on all ground strokes and volleys. My problem is that with this racquet, my serve is very inconsistant. My flat serves sail long, my kick serves fall short/or long. I've tried adding 2 gm of lead tape at 3 and 9, not much improvement. Any other recommendations? Thank you. I am demoing at the same time the Yonex RDS001/002, Dunlop Ae 200, Wilson K 6-1. I have no problems at all serving consistantly with these, but on ground strokes the Fisher just feel better.
