Oh, I forgot one, the Wilson Ultra II. It was way ahead of its time! Aaron Krickstein played with the standard model and some other pros used the midsize. They even made an oversize model. I have added a photo of it if anyone want to see what it looks like
Dunlop Max 200G. It was pretty cutting edge for its time. The injection molded frame transmitted very little vibration while allowing you feel every shot. I occasionally break it to play and it still give me 85 square inches worth of happiness. Navratilova jeopardized her Yonex endorsement contract by playing with a 200G, but she removed the paint and logo. She didn't fool anyone.
