I've used the Aeropro Drive a bit before, and I really like it. It's not too powerful, so I don't have to worry about overpowering the ball as much as with my Prince O3 Red, but it's also solid and quick feeling (my O3 feels kind of clumsy). Anyway, would it be worth demoing the Donnay X-Red or X-Dual Core Gold? I don't know anyone who's used them, so I'm wondering if someone here can weigh in. Thanks.
