Where is the sweet spot?

This was one of the biggest debates our team had for the design phase: what level stack is going to provide maximum scores most consistently? Not in theory, but in practice, where tall towers tumble, and take time to make that could have been spent better.

Obviously the best teams will do six with RC consistently. But is it really wise for everyone to keep trying to stack six?

Anyway, we eventually settled on three. I'm curious as to what everyone else thinks. I'd do a poll, but I don't know how.
