I start all my young horses in a simple loose ring snaffle and have just recently been using a d-ring when they are just a bit further along in their training. For all my well broke horses, I use a bit almost exactly like this:
But of course, I do lots of cow work like roping and cutting where I can usually only use one hand. This bit works tons better for neck reining than a snaffle does, it is less confusing.
I use a Sweet Six gag bit on my filly. She absolutely loves it. It is great because it has enough of a bite to stop her but is is gentle enough on her young mouth. On Chase I use a twisted full cheek snaffle or atleast for this summer I am. I had jumped him up to a better bit with shanks but he had an accident last fall and had to be retrained into a softer bit. Hopefully by next year he will be back to normal.
