Hero pushes and expects to be called by a set of 5's - his flop call on a draw heavy board and against 2 opponents isn't likely 2pair, set, or 68 and his turn bet looks like he has a hand now and wants the field thinned or the draws to pay - best guess is 56 or A5s. He might have played those more aggressively on the flop against 1 opponent but since the pot was large, it was multi-way, and the odds were good he decided to just make the call.

I'm fine w/ the flop call. I prob would lead the flop w/ a bigger bet - like 175.
