I deal with the same thing. We're in a basement and have to deal with stairs. It's not bad if you have someone to help you. It's actually not bad at all with two people. I say this but me and the other bass player are both pretty big guys (well tall not big. about 6'4") I carry the 215's by myself and they're the size of a 412. Plus you can always wheel around the 810. It's just the stair thing you'll need help with. Once you get used to it it's not bad at all.
so do you just have someone on top pulling and someone on the bottom pushing? I'm a big guy, basically the same size as Laz, and it's not really the weight as much as the huge pain in the ass.
