Calling due to odds in the blinds

[ayecappy]

I play in the 1/2 6-max at party and the situation frequently arises where where im in the blinds and get very good odds for calling, either in the BB in a raised pot with cold-callers or in unraised pots in the SB with callers often getting 5-1 or better. Assuming the pot wont be raised again very often and this isnt a spot to "vary your play", how much can you lower your calling standards against weak opponents?

I use pt and gt+ ofcourse so my preflop play is pretty much based on the players. Also the rake(i guess its considerably higher relatively to the 5/10 that most ppl here seem to play) must play a big role in playing marginal hands, especially out of position even though the players are incredibly weak?
