PF: I dont think I should be raising AJo OOP against this guy, I havent seen him fold to any raise PF yet (except a 4bet to $10 when I had AA).

Flop: He leads out small all the time. If you call he generally will minbet or donk bet on turn. If you raise he seems to come out strong on turn for at least 1/2 the pot and sometimes a small overbet. I've never seen him 4bet flop.

Turn: I was expecting a strong bet from him, hence I checked because he might have raised any bet I made and I didn't want to inflate the pot.

Like I said in my notes I have seen this guy make huge bets with very bad cards a lot of times. His range could be 96o to TT. I have never seen him go all in but last 15 or so hands he has been making heaps of out of line plays like betting $10 on a $2 flop and open-raising 10BB PF.

Kinda seems like a lot of info but I did have some decent reads on him. Given the reads I was leaning towards calling but I have no idea, especially for so much BB.
