Hero ???

I have no reads on either villian. What to do on the flop? 

After 3 betting pre-flop and potting the flop I think CO very often has AAxx with NFD or a AKQJ type hand with a FD. 

UTG could have a flush draw as well but i think its less likely given i think the CO often has one so id say UTGs range is weighted toward 9TJx hands.

Against those ranges we have about 33% equity which would make this a jam. However the times we run into a better made hand obviously lean us toward a fold. 

Also given villians ranges hit basically every turn card in the deck calling and waiting for a safe turn isn't a great option. We only really like a 2, 3, 4, 5 of not diamonds. Even then a 4 and a 5 of not diamonds we still have to worry somewhat about a straight. 

Am i correct in folding here or is there a better line I can take?
