If you never give the horse a chance to make the mistake of nipping (and then correct them) then they will never learn that it isn't allowed because they are never told not to. Personally I would rather know that my horse isn't a nipper because I have trained them not to be, instead of refraining from something because I'm afraid of the outcome of the action.
My lad is fed treats regularly but because he has had a good smack accross the chops the one time he did try to nip, he no longer even tries. And because siad smack was administered properly he is not head shy either.
