Backhands: spinniest to flattest
Obviously one and two handers are judged together.
Nadal has got a lasso-whip forehand, and his backhand might be the spinniest as well considering how much he moonballs it nowadays. But then again that might just be open-racket-face moonballs.
Rank some pro's in terms of the spin of their backhands from spinniest to flattest. I think Gasquet's backhand is up there.
