Tough turn decision, big draw

[shpongled]

It's been a while since I've been faced with a big decision this marginal. I have a good read on UTG+1. He almost certainly has a set here. I've seen him smooth call the flop with a set plenty of times, even on draw-heavy boards. I haven't seen him play draws aggressively very often. No read on BB.

Note that I need 29% equity for a call to be correct.
