Hard to compare those two. The graphene xt speed pro is a much heavier, stiffer stick. A better comparison is the graphene radical pro vs the xt speed pro. I've played with both. I'd say the radical pro is a far better racquet. With the 16/19 string pattern, it's easier to get spin and it still has about the same amount of control. You can get spin with the xt speed pro, but you need more racquet head speed with the denser string pattern. For me, the radical pro is slightly or much better on every shot: serve, return, ground strokes, and volleys. The maneuverability probably has a slit edge to the speed pro, but not by much. It's a no brainer in my mind to go with the graphene radical pro. This is a seriously good racquet and leaves room for customization (adding leather grip, lead tape, etc).
