MMM for my E-revo now or......

I have had my new Traxxas E-Revo for a month now and the stock setup bores me. I have been reading up and down and can´t decide. I would like to get the Mamba Monster Max esc and try with differnt moters (guess I´ll end up with a Neu). Would it be better to wait with the MMM - It seems like it´s having issues -and get ex. a Mamba Max/feigao combo until these issues are cured ? It could take months. I´m bashing and running 4s lipo (hopefully 6s later on)

Whats your opinions ?

Regards
