hobbywing ezrun 150A vs Mamba monster

[fastbaja5b]

I recall when I ran a X1CR buggy with a Medusa 36-60-2000 on 4s, the HW 80A speedy felt a LOT faster than when I ran the MMMV3, and I made sure everything was set up alike.

Now hearing more and more failures with the MMMV3 and yet to hear of a HW speedy failing, is it worth my while ditching the MMM from the flux and putting in a HW150 speedy just so my set up is reliable?
