200NL AT top two vs turn c/r AI

The CO is pretty weak tight post flop and I've been punishing his LP limps quite regularily. The SB is 50/4.5/passive post flop over a small sample. No notable plays from him earlier.

Easy call or easy fold?

Insta-call.

call and he shows a worse 2 pair much more often than a set

I expect to see AK/AQ/AJ here a lot.
