I don't like it even if you're 99% confident he won't have a flush draw because if he has a low pocket pair you're giving him another chance to hit a set, low pocket pairs sometimes call one cbet on the flop (well, prob not this one), and prob more important is the turn is likely to scare him even more instead of make him want to bluff. Maybe on like a J 7 2 rainbow flop, but I'd still usually bet that flop to be consistent with my cbets.
