Just got back from playing with three different racquets, BB London, Pacific Vacuum 90, and the Volkl X8 315. My main racquet is the the London, and it is stellar for me in all areas except my 1hdbd slice. I thought it was just the fact that I lost my touch due to long gaps in not playing, as I seem to always float them a little. Today I tried two different sticks, the X8 315 and the Pacific Vacuum 90. With the X8 315, slicing was pretty effective, but with the Pacific Vacuum, slicing was insanely good. What racquet attributes enhance the slice? I would like to customize my London's.
