motor for 2s help?

Hey guys finished with racing since it put me in a hole with $$. Im buying the hyper mini st-e to messaround with and it will only be used for bashing. I'm trying to find a sick setup on 2s lipo but am getting scared cause everyone uses 3s lipos. The 2 motor systems I have in mind would be a MM/Fiegio 7s 540motor or a Novak hvpro 6.5 combo!! Which would be better for bashng and most fun out of the 2? Or is there something more poerful?
