Venom LiPos vs. Apogee LiMn?

[TypeR #126]

I'm trying to decide between some Venom 1800 20C packs, or some Apogee Magnum 2200 packs for my MT2 (both 11.1V) that I will be running in parallel as a saddle pack.

These seem to be the best options based upon the size constraints for my preferred mounting points.

My questions is how do they compare to each other? I have a few other Apogee packs and they seem to deliver a pretty good punch, although they don't always deliver out their full mAh rating. I don't know anything about the Venom packs. FWIW, the Apogee packs are also $20 less, each.

Thanks!
