I would say go without it, or maybe just use it say once or twice a week or something.
Mitch and I are having the same problem at the moment, but we have started without any extra equipment so he's learning fast what I want.
What happens if you growl him and keep asking him down when he's bobbing his head around?
If Mitch starts that and I growl him and keep asking him down (Just the standard "AAH!") he puts his head right back down, I don't go easy on him at all because I don't want him thinking he can walk over me.
So far we've been working on it about a week, but he's getting far better.
Good luck, just keep trying :)
