Hey I completely love Cass but a lot of that is the implications of him existing and what that means for the SPN universe and the rest of the show. Plus you know the shallow part of me who things he's one damn fine looking man (SPN rarely has girls that I like, although the Crossroad Demon(s) are always smokin'). So I imagine it's just fangirls latching onto another hot reaccuring *male* character.

I do prefer HQ but like you said I can deal with 350mb. But HQ is fantastic for vids, art etc. So there's that and plus a lot of stuff is getting ripped off of HD tvs these days so it's getting the benefit of that.
