Product Reviews: "Wow! This is an extraordinary racquet to which I'm likely to switch from my Speedport Blacks (string hole 12/6-speedport 3-9 hybrid; Silverstring 1.20/VS Team 1.25 hybrid). Outstanding power and placement from baseline; better depth control and spin generation than I would have expected from the demo's multi string job and from the speedports all around. Amazing lateral placement on serves, but confident depth control will take a little longer. Returns were consistent and stable against an opponent's heavy first serve. My Speedport Blacks are leaded at 3, 9, and 12 - and counterbalanced in the handle - but the stock weight and swingweight of the Pro White feel just about right. The denser string job, heavier weight, and slightly greater flexibility of the Pro White provided the control, stability, and comfort I have been trying to tweak the Blacks to produce." - Chris, Los Angeles, CA
