I'd go with either CIMs or MiniCIMs. BAG motors have such a high RPM that they self-destruct their internal bearings. That is the reason why our shooter needed to have it's motors replaced so often. Also, if you aren't stalling the RF-775s, they are fan-cooled so they shouldn't get very toasty under normal working loads. CIMs are able to cool off all right because of the surface area and size of the motor. BAG motors just overheat all the time!
I agree that pulling 100 amps continuously from a motor means that you are doing something wrong. That is nearly the max threshold of CIM windings!
