Big combo draw on turn vs 2 villains - shove? (2NL micro)

[rowhousepd]

I'm raise in CO to try to isolate a weak EP player but get callers. Both of their stats are vanilla and I haven't seen them play enough hands to get any reads. Turn brings a big 15 out combo draw: nut FD, a well hidden OESD, and I still have an A overcard. I don't know what they might have, but I'm thinking either could be drawing or maybe made a small pair on the flop & didn't want to bet.

My question is: after it's checked to me on the turn, do I shove? or just call and hope to make one of my combos on the river.
