My Fischer Vacum Pro 90s are 411 grams bare. Thats with no grip, no strings, and no lead around the head. Add to that a leather grip, overgrip, strings, and 14 inches of lead at 3 and 9:00 positions and its my starting point. I may be adding some more tape at 3 and 9 as it is feeling a little light lately. As of now they are 456g unstrung. Most of the added weight is in the handle. They dont feel heavy at all to me. Weight is not really ans much of an issue as where its placed. I am not a big fan of head heavy racquets.
I have never understood the big love for light racquets. You just end up muscleing the ball all the time and tensing up you arms and putting strain on the body.
