Which MGM would work well? thanks guys!

The 16160 would work.
I'm not sure which would be best,the MGM's have a few little software niggles,my 24160 has this thing where if you're freewheeling and blip the throttle it brakes hard for a split second.basically it tries to bring the motor speed down to the speed it would be at the low throttle input.Setting the range of neutral zone high solves it but leaves deadband on the throttle.a one-way bearing solves it obviously.it has nothing to do with the drag brake or freewheel,they're both off and they're unuseable settings anyway(they brake hard when you lift off).
otherwise it's a good and reliable esc with excellent lvc,i like mine alot but i use it with a one-way and mechanical brakes.

Up to you.
