I might be alone on this, although I find armored valks cool, they are not as cool as stripped down valks. I mean, once you put armor on, they look more-or-less like typical bulky robots. I don't know, they just seem to lose their aesthetic appeal to me. However, I find Fastpacks a good balance.
BTW, I voted for Angelbirds. Come on...who doesn't want to see a valk in a schoolgirl sailor suit paint scheme?
