When Dave made the comment at kickoff something to the effect that just because you were given (14) motors doesn't mean you have to use them all, we started laughing. A couple years ago we used all but one, and we considered just putting it on as a counter weight
Even though the 2 new CIM's are more powerful, we are usually traction or control limited and not power limited so I'v guessing we'll use 4 smaller ones for our drive train to keep things common and use the other 2 for fun stuff.
