I would get the Medusa over the CC Neu. You will be able to pick a kv rating that would better suit your set-up. I'm going to use a 8XL in my Revo just because it comes with one and why not use what I already have right... I'm 90% sure I'm going to save up for the MMM but I have better luck with the eZRun ESC's so I might go with the HW 150A. The only reason I've heard of them frying is when people mess around with the timing and punch so I would just make sure to leave those alone.

Oh and one more thing, if I were you I would try to run 5S or 6S. From what I've read a higher voltage / lower kv set-up will be more efficient.
