I think I would probably call based on the fact that I can dominate AJ and also given his vpip, pfr - he is a volatile player profile who can do silly things like raising merge or weaker pair+draw.

What if we are dealing with 70/3 type of guy? Vs that player I would prob find an exploitative fold based on the fact that I dont expect him to be raising merge or even AJ and also that he is more like a passive guy who isnt bluffing nearly enough. Also that his value region - twopairs+ is pretty wide due to his vpip.
