Two-outer with a huge pot at a maniac table

[turaho]

This table was crazy... previous hands had players capping with A6o, cold-calling three bets with 54o, and raising the turn with inside straight draws. A few big pots were dragged down with K high. Interested in your views on flop play...

<font color="blue">I have 22-1 odds to spike my set on the turn. I'm getting 13:1 to call here... will implied odds supply the rest? The two preflop raisers are still left to act (I suspected SB was planning to check-raise because he had a bad case of the FPS). I wouldn't have been surprised if the flop ended up being capped. Should I have called two bets?</font>
