If villian were solid, I think I'd actually prefer to see you bet 5th - and consider folding to a raise. Not saying I'd fold to the raise, but once you check 5th he's betting any pair w/ 4 low, any small 2 pr, or anything better. Aside from the info that you gain from his reaction to you betting 5th, you set it up to where he'd possibly fold 2 small pair on the river.

That's a tough spot. You really don't have much choice with your big draw, and can't really be faulted for acting any number of ways from 5th on.
