600NL - Top pair + flush draw + gutterball

[SamG]

Villain is 52/8 and plays too loose both before and after the flop. I was looking to play pots with him.

Normally I would raise the flop and be happy to get my money in. I wasn't sure if I could make this opponent lay down a better hand, however. Should I raise here or just call and try to get the money in if I hit?
