The teams that did tended to use them outside of the drivetrain.

OK, I can understand not using the large CIMs because of their larger size and weight, but that was not the reason given.
According to the motor curves I have, the large CIMs seem to be more efficient (power out divided by power in) than the small CIMs. Perhaps I have the wrong curves? Or perhaps it wasn't a question of efficiency but rather the higher power output of the small CIMs ?
Is there someone from Team 75 that remembers this analysis and could fill in some details?
