I hate pre but I see why you might do it. I think the call/fold decision is way way closer than most everyone else. I think you're going to see a ton of flush draw type hands that we beat and just random air - but the only problem is those flush draw hands actually have a fair bit of equity. Add in the hands that beat us already and it's probably a fold, but I think it's pretty close.
I guess I tend not to try to bloat pots against these kinds of villains with really marginal hands, because it's so easy to get their chips when you have actual legitimate hands.
And... what's so wrong about pot control?
