where the head goes the body will fallow, with less force, I don't realy like them either, I've never had to use a pinch collar either though, I don't let them do it wrong and it's usually not a problem, don't let them pull the leash tight, when they do, don't pull back steadily, yank back, do it walking forward, backward, sideways, do it without a leash, just make them stay, then adjust your position, turn around or whatever, move a bit, then make them heel, don't stop working heel, till they completley understand that when you say heel, one time, their right exactly where you want them.
