Would you respect this bluff?

[T0ne D0wn]

I have opponent at 25.7/15.8/1.87 over 2k hands. He can tilt and play horrible sometimes. He respects my game, wont play me HU and I run at like 22/18. Hes not tilting right now, and he has never caught me making an excessive amount of bluffs, but he knows I am an agressive player.
