Pack recommendation for Revo

[BrianG]

My E-Revo weighs 8lbs without batteries and I want to keep the weight to a minimum, so I was looking at this pack (very last one on the page, which is sold out right now): 5s2p, 8Ah, 80A cont, 120A burst. The runtime should be quite long, but is this a good pack at only $165? I'm running a 10XL, Quark 125B, 16:1 total gearing, ~10 lbs with batts, standard maxx tires. Another plus is that it fits perfectly in the space I have.
