I made a vex robot with that exact functionality.

Yep. I knew about this option, but measuring current draw appeals to me more. It seems as though it would be "simpler" to get a definitive answer as to which gear the robot should be in. 1126 and 33 have succesfully done auto-shifting on a 4 speed transmission using the encoder approach.
