wa/wb seems like the best line. I don't see this guy capping with AJos.

How many hands are these stats over? If he has 20% pfr and 20% vpip I guess they are probably over a very very small sample. That makes most of this data inconclusive.

He may be quite LAG but has had a small amount of cards meaning you get paid by ATs / AJ.

I c/c most of the way for a real tag, betting the river when he checks the turn as he is probably checking underpairs if he plays the turn passively.
