Hello clandestineAl,
Well if that's true and he has been really active on the tables. 3betting you a lot then I'd just 4bet than Call being OOP.

And then reevaluate further actions. Most likely we could even consider going broke but of course there is still an option even to fold if we don't expect the opponent to continue with a lot worse.
The Call vs 3bet being OOP ain't gonna bring us much since we can't really play that profitable being OOP. Also we wont hit often enough anyways.
Best regards.
