simple situation whats the standard line here?

[shpanko]

this is either a set/two pair or a combo draw. Nits like this don't cold call pf with a very wide range. This is a set a lot, he's raised us the pfr with a player left to act, it's not like this is HU. It feels week but against this played I fold, he doesn't have a lower overpair and he rarely has a draw. I supposed it could be 66/77 but meh I think this is a set more often. I also guess the decision depends on his perception with you, what's your image at the table?
