Ok, as soon as my withdrawal makes it into my Neteller account I'll have SNGPT, but until then can someone give me some general advice on consistent PF limpers and mini-raisers on the bubble?

Every time I have what seems a marginal push, someone comes limping in front of me and I can't pull the trigger. Assuming limpers/miniraisers have greater than 8x BB, what do these players do to your fold equity? Can you just treat their limps like a check and push anyway? I feel like I'm squandering a lot of good situations by being afraid to push over them.
