I also don't like correction collars. Mikko's herding instructor has him on a choke just in case, since he is very obsessed with the sheep...we've only been to two lessons but it kills me. Next lesson I'm going to ask if we can try him on his buckle collar with high reward treats and see how it goes. If it doesn't go well, I am going to buy one of those collars that tightens only to a point, so they can't slip out but don't get choked either.
