Question: Is the pre-mixed Thinset any good or should I stick with the stuff I have to mix? The drill I have is starting to take the punishment from all this Thinset mixing!

Oh and by the way I installed the new 1/2 inch plywood along with the Wonderboard. Tonight I just leveled any "dips" it had to a nice smooth surface, I'm shooting for this Saturady to install the tiles!
