I've played with A LOT of rackets and NOTHING produces spin like Fischer Pro Tour Extreme SL (the 325g version)
It is a 27.4 inch, 95sq. in and 9 point head light, flexible racket with open string design ( 16x18 ).
This one is low on power (alot of flexibility in a head light unit at under 12oz will do that). In fact, when I got that racket I had to put it away for few months and play with more powerful Pro Tour FT (same weight but more stiff and less headlight at 98 sq. in.) to develop my forehand to produce more power. Switched back to Extreme just two weeks ago and the spin is amazing (though now I was able to send all that spin all the way to baseline) - sending those short balls cross court is a pleasure - the racket swings around its handle as if on it's own and makes achieving insane head speeds very easy.
P.S. I played with Prince O3, Flexpoint, RDX500 and all the Babolats and Wilson Prostaffs - not even close...well maybe Pro Staff Classic 6.1 was close, but it was way less maneuverable at 12+oz.
