I bought 4 of them for $40.00 each from some dude who needed money thinking I'd change the pallets to 4 3/8 but never got around to it. When I got them they had Alu Power Rough mains and Babolat VS crosses which I thought was a bit much for a recreational player but it never crossed my mind they were possibly pro stock. If that's the case though wouldn't they have one of the pro stock codes in the throat?
These don't really show anything but here's one of the racquets.
