I'm in the camp that I think open cans makes very little sense to what the OP described.
I'll throw the ones I've used for years (and I've tried most of the mentioned ones) .. the KRK 8400. Warning, if you like hyped cans you won't like these. They are flatter than a sewer hub. But the best part is I've had the same pair for long time. You can get the parts at like zsounds for everything so that you don't need to replace. I don't know about anyone else but my cans get worn pretty easily. Pads, chords, the top portion, all replaceable.
