Hi everybody, I'm getting a E-Maxx this X-mas, and I figured I need around 4 pairs of batteries for bashing.

But I can't decide whether to get the Epic 3000's ($19 for a pack) or the Orion Super Duty Plus 3000's ($55 for a pair). Are there any significant differences in their output performance etc? Btw I'll be getting a Novak Ionic charger. Any help is appreciated, thanks!
