what MGM and neu combo will work for me?

i am looking to install a neu and MGM compro system in my emaxx 3905. i will be running 2s lipos and want to know what will be the most stable system for the truck. i will not change my mind over the MGM and neu combo. like i said i will b erunning a pair of 2s lipos in the truck and there is no change on that either. i will not be modding the chassis at all to wrok with bigger lipo packs which is why i am limite dto only 2s lipos.
