Need Help picking new Brushless System

Hi, I am very interested in getting a new brushless setup for my e-maxx. I do not have enough money for something like a plettenberg motor or schultz speed control. I am currently running the Novak HV-Maxx, but have ran it into protection mode too many times by overheating it and I think the bearings inside the motor have gone bad.

Anyway, I want to run 8 cell matched packs and either a Feigao 10L or 9L and I wanted to know how much of a diference I will notice using a speed control like the BK Electronics 12020 Warrior which is rated at 120 amps versus the BK Warrior 9920 which is rated at 99 amps. Is this a good setup? I heard the Feigao motors have the best bang for the buck.
