i geared my toons up in blues/crafted stuff before i started heroics. Most of which i got questing, made or bought of the AH. Once i started Heroics i hit UK, DtK, Gun, CoS are the ones i try to get in every day. i Skip VH, it's a pain and i don't like boxing it. UP is ok for the first 2 bosses. 3rd is trouble if your not geared well and have the strat down. and i don't like AN or OK so i generally pass on those as well.

And i've also found what is easy to do in a PUG is not generally easy to Box, which is why you see people doing different ones.

I also sneak my alts in to Raids when i can, as i raid 4-5 days a week, so they tend to end up with alot of mis matched epics.
