If you have a regular nylon halter, you can hook the reins to the side d-rings and is easier to get your point across than if you have them hooked to the ring on the underside. However; if she does not tuck her nose and bend at the poll, when you apply pressure to stop her, the halter will slide farther up on her face and could create all new problems. I never saw the point of spending lots of money on something new when what you already have works just fine.......LOL but that may just be me.
Exaclty what she said.. You are teaching the basics, and any flexion you can teach and practice will be given even in a halter. A rope halter does work quite well, and better then a flat nylon for a vareity of reasons.
As for the finer cues, that's more of when bits step into play, but at that point a person should be past flexion exercises, and be working on specific tasks.
