i am not scared to fold kings preflop. if the opp is the type of guy i can put on aces 70% of the time, i will fold if i haven't committed too much yet. I think here is a pretty perfect spot to fold, if he doesn't have aces 70% of the time here, i'd be pretty damn shocked.

i used to play full ring. in full ring, i find it more clear when to fold kings, and I have several times. i've gotten some shorthanded under my belt now, and i've yet to fold kings. for what its worth.
