fisherman's delight - bet or check the turn, though

[Eaglebauer]

UTG is 60vpip+ lagtard and MP is 50+ call station, as is SB. Is this a clear bet or do we check because we picked up the nice draw and might have overplayed the flop? Frankly I didn't think much of utg's flop 3bet given his lagtardishness and thought could be j10 or worse.
