I'd like to mention one more thing.

You said donk leading is a line you never really take against him. Do you know if he's seen the type of hands you've lead into other players before?

This could help in determining what he would think you hold when you lead into him, and help determine the best action.

dranger7070 and I were discussing the hand and he also brought up the point that c/r'ing seems like a resonable line as well. This is something I left out of my analysis. dranger mentioned that because of your history, your c/r may be seen as a bluff alot, depending on how often you c/r and what hands you've shown down after c/r'ing.
