That is close to mine, but your hand is turned more parallel to the handle. Mine is more perpendicular. This would not have any effect on how you define the grip, but it seems like an important difference. Your index knuckle might also be turned very slightly more in the eastern direction. Maybe only by 15 degrees or so. (I am not saying I think it is eastern, I just do not want to influence the poll by saying what grip I think I am using. Especially since I obviously don't know.)
The angle at which your hand is holding the racquet seems really important, and I don’t get how you can define a grip as more or less extreme without taking it into consideration. If you define grip by reference to the index knuckle, it looks to me like my grip would be defined as slightly more extreme than this one. However, since the hand is more parallel to the racquet in this grip, the palm ends up at a more extreme position. I would guess this grip would actually play more extreme than mine, even though it would be defined as less extreme. I might be totally wrong on this. Does this sound right to anyone else? This might all seem pretty nitpicky, but I really see a huge difference in the way my forehand feels and the trajectory of the ball for very small grip changes.
