I know some players here incluided me, they have the same probs with the wedges some times. Ball is running away like water is fallowing a mountain down hill. Or stops like falling stone in the half of distance.
This is the net working of wgt and flash player. Its not the reason we have to controll our PC"s. The game platform need a big replacement.
Same i saw this in to much CttH games. Lot of shots are very close to the pin, and than you have 2 or 3 hits you dont know why the distance is a big incontinence in this moment.
