I agree with Fed. I think that is what got me to the point I am at now. The PSTGT is kind of the same as well. It is a player stick that lets you manhandle pushers with accuracy, but also has tweener power that lets you hit with the higher level guys.
The donnay is actually easier for me to use than the pstgt. Before I got hurt I beat an ex dII guy with a nasty 1hander. It was not that I beat him, but more that I beat him with patient and consistent strokes. Of course I went big now and then, but with the Donnay I find myself in longer and longer rallies than before. And this also applies to the 3.5-4.0 guy who is trying to wait out the storm and watch me mess up.
