I need a middle of the road BL setup for revo...ideas?

[R00ST]

So I want a reliable BL system that can push the revo to 40 but still have low speed controllability. I am going down to one rc and was set on the slash 4x4 but I am thinking I want a revo again as they are much more capable offroad/climbing. I do enjoy slamming trucks and running on the street (and the slash would excel there already being lower cog/lighterweight) but I think the revo will be what I buy. Because I do want the truck to be able to do SOME slower stuff (not .5mph, but I dont want the truck to be doing the cogging jitterbug at anything below 5mph).

So...should I look into the novak systems or are those really not that great these days? I need affordability and would probably only be running 4s. Are those 80A xerun or ezrun (w/e they are called now) easy to get and reliable? How about say a 10xl with that combo?

I had considered the dewalt setup but those motors are huge/heavy and I figure I may as well go BL from the start.
