Reads: Firstly, the original raiser was doing some really stupid things, so I wasn't too worried when check-raising the flop big. Main villain though was pretty competent, somewhat aggressive, but occasionally did some questionable things. His turn raise was pretty quick though, only took about four seconds, which can often be a sign of strength.
So as well as the obvious question, how often do you guys lead the turn?

fold pre, lead flop.

Turn is a fine b/f, although leading flop is superior. I find people don't bluff here.
