I don't care for raising the flop either, Isura, unless you want to gamble to a flush draw plus, perhaps (doubtful), a little something something. Seems like you are the type who likes to chop away at donkeys through small pots and knock them off later when you have the better of it. I like your idea best. Make it 40, fold to further aggression.

A lot of times, donkeys like this won't provide further aggression, but rather, will just call and then bet out small in the end. If that's the case, I suggest checking the turn and then calling depending on what your opponent bets (say, if he tries something like a bet of 15 on the river, then what the hey, maybe he's bullshitting and you get information that way).
