Best switch I made was from the first Kneissl Toms Reach Machine to the 2003 Fischer Pro No. 1. The first Toms Machine was great but the Reach Machine was an unwieldy beast. By the time I got around to chopping an inch off I was over it.
The Fischers were a dream to play with. They didn't have the zero tolerance but the covers had a sticker with the specs written on it so I found three as close as possible. They were comfortable (even with TNT at 67 lbs) spin machines that were maneuverable and still had nice plow through. I stuck with them as long as I could then went to the Tecnifibre 315 V02 Max (same mold) but they never captured the feel of the Fischers. Personally I think it was the ceramics that made them feel so sweet.
The only racquet that evokes as much devotion from me is the Head Pro Tour 280.
