What do you think on a Tower Fun 51, a TT GP-42 or a TT Pro-46?

I've read that the plain bearing TT GP-42 is plenty of power and then there are others who think the brute power of the TT Pro-46 is the way to go.

If I don't need unlimited hover/vertical, I'm thinking the GP42 is going to be plenty of fun.

I got a friend who has a Tower Extra Special profile with a OS 40LA, and its all over the place and quite capable.

Any thoughts?
