Castle MMM 2200 in a Gorilla E-maxx

[Klausen]

I am currently running the HV6,5 in my E-maxx, but have thought of changing the system to another.

Will I gain anything if I change to the Castle MMM 2200 system, and what about the batteries. Will I need an adapter to let them into the esc?

I am also thinking about the new RX8, and one of Tekins motors, but I am not quite sure what motor that should be. How is that system compare to the HV6,5 and the Castle soultion?

Any help on this is greatly appreciated.
