The Right Direction :)

Your pictures really help make clear what you are saying. I use very much the same methods as you and also work alone almost entirely. I find it easier most of the time since I don't have to hope the 2nd person can keep up with my intent when I must react quickly for some reason. However, for people with access to a 2nd person there are places in training where it takes less experience (and time ) if there are 2 people working together.

I could not manage these days without my round pens. I have a small one for starting and a big horse size one that doubles as a foal paddock for starting work in (but not with the cart, that I do in the open) You can just get a set of riding bridle cheek-pieces and buckle them into the bridle that comes with the harness, or even use a riding bridle- but I don't use a bit at all until the horse is actually going freely
