Even though a closed back headphone will lead to less bleed, theoretically, I find that I like open back headphones so much more because of ear fatigue issues. It also seems to keep me from being eager to take one side off.
That said, isolation headphones like Vic Firth are great for tracking drums even if they sound sort of crappy.
Seems to be helpful to have a few different types of headphones. For example, I have some Ultrasones that seem very flat, and I which I like most for general tracking. However, I sometimes tend to like AKG240s if I'm recording myself doing acoustic/vocal stuff, because of how they make the sound cut through a bit differently...I guess they probably have a bit of a peak in a certain part of the spectrum that makes pick attack and some syllable sounds pop in the phones just a bit more.
Somewhere I have bunch of Sony headphones in various states of disrepair, not sure the model, but to cover when a band doesn't have any phones. I thought they really sucked, but if budget is low you have to do what you gotta do.
