Which "felt" more powerful? Seems like the MMM can pass some serious current, and feed the motor well.

What's the current rating of the MMM?, I know the MM V2 is rated at 200A continuous so presumably has a higher burst rate than the MGM 160. The MGM is obviously rated at 160A's continuous and 200A burst, so the MMM if rated the same as an MM V2 would feel more powerful because it is.
The MM V2 has it on price, especially if you then go to the MGM 224, but the MGM is available in a waterproof version, not a problem for you dear old boy's from the sunny states but useful here in the UK.
