So far, this is all good enough for me. Stich played with a light racquet. Thanks for the info.
Next question is, Why.
He had those beautiful, classic, (read heavy racquet) strokes, nothing like modern, whippy, high racquet-head speed stuff you see these days that might require a lighter racquet. Obviously, only Stich can answer this, but we might be able to see something from his game. I don't think I've seen him make shots guys with heavy racquets don't make, but I have seen him slap at the ball when he's having a bad day, as when he lost to Agassi (who was having a very good day) at the USOpen in '94, which is what I think can happen with a light racquet.
