EV playing short time in crazy games?

[lewdjunglist]

I have a question, but I'm going to give some background info first. Sorry if this is too long or the wrong forum, but I thought it best applied here.

There's a home game I've played in that has a lot of loose players pre flop. They will call raises of 10-20xBB often with junk starting hands. Straight draws (all kinds), weak flush draws, and BPGK/NK or MPGK/NK are often called for odds that aren't right IRT pot odds or implied odds. Usuall the game starts late in the evening, and goes until 2am-3am..ish. There are some tight players mixed, but most are passive. There are a few agrro or LAG players who are pretty decent. A few of the more agressive players often open to 17-25xBB preflop. Stacks range anywhere from 50BB-200BB, more often in the 100-150BB range though.

My question is, playing for such a short time (2-4hrs) with a solid TAG game..do you think this is profitable? Normally if there weren't the large BB preflop raises I'd say yes. The enviroment of the game seems like it would create high variance.
