I'm almost to the end and I'm working on gags. I've got everything covered except I was reading that if the rider finds that the use of two reins is too cumbersome then only the gag rein should be used. I've never used a gag, myself...never had the need, so I'm having a little trouble visualizing what happens when it's only ridden with the gag rein. For example, would you ride it with one hand like a curb, or would you ride it with two like a snaffle?...the presence of shanks and the absence of the curb chain is what's confusing me as to how it works (what it does).
If anyone can help clarify or has any good websites I can go to I'd appreciate it. I've already been to that "Sustainable Dressage" website and the ones that show up on Google (it's hard to search, though because of all the bits people have for sale that clutter a search).
