$3/$5 Bare-Ace flushdraw on monotone flop OOP

[bilbo-san]

I have about $1200 and covers the table. I've been pretty aggressive pre-flop because there are two MASSIVE calling station donks on my right that I keep trying to isolate (with good but mixed results).

The two guys to my right are literally limping 100% of flops, and if I raise, I've taken it down preflop about 50% of the time, and on the flop I can read them pretty well, so I've been raising almost anything playable from MP on.

The main villain in this hand just sat down to my left, and has $300. I see him as a tight but very unimaginative player, and I'm pretty sure he does not get the concept that just because I am loose preflop does not mean that I am stacking off light post-flop.

Two limpers, Donk to my right min-raises (he does this a ton), I make it $45 with A[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/spade.gif[/img], guy to my left calls, every one else folds.

Flop is 8[img]/images/graemlins/heart.gif[/img]6[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/heart.gif[/img]
I check, Villain bets $40, I raise to $150.

Thoughts? I liked this better than betting because I'm going to hate (and be without a plan) on so many turns if I CB and he calls, plus the size of his bet made me doubt that he had a flush here.
