believe it or not, Warrior vs Paladin has some info on bear tanks.

also, bear tanks? i've been bear tanking for a long time. sorry, but swipe hitting more targets just makes things super easier and has nothing to do with viability. i tank with swipe on multiple mobs always. before, when swipe-multi-mob-tanking, i would swipe, tab, swipe, tab, swipe, tab, etc, just to make sure everyone got hit their fair share of swpies. now no one gets left behind.
