Need help deciding what to power the E-Revo with!

[R00ST]

I have my E-revo almost done. I currently have two novak HV systems, one new, and one that has a few issues (acts like its cogs...isnt very smooth) I have never run this in a maxx or heavy monster, but it did have a lot of power in my xxx-s! (not a good comparison I know).

I am thinking I will want more power than what the hv-maxx can provide for me.

What are other comperable systems to the hv in price? I want somthing SUPER reliable. What about these new MGM controllers? I dont follow brushless too much, last I was checking around everyone was running the hackers (8s I beleive in the maxx's, with comp controllers that were frying).

I would like to spend no more than 300 (less is better) and I would be running 12-14 cells (14 most likely)

Can anyone reccomend a setup for me?

*edit* I also want to add that I like to do some slower paced rock crawling and true offroading with my trucks, so if there is one with a lesser showing cogging, that would probably be the best. How is super low throttle response on these non-sensored motors? sometimes I like to just slowly crawl around and up curbs and over rocks, would this be possible, or would it be 1/4 throttle or nothing?
