When I said the Chris Cox bit was less expensive, it isn't cheap by any means. It's $75, and does have copper added. It appears by the looks and description on the site, to work very much like the myler.
I'll probably still go with the myler bit because it is sold at our local tack store and they are wonderful about helping with selection and fit. Also, with shipping and handling, the Chris Cox bit will probably end up costing me more.
If anyone has used a Chris Cox snaffle bit, let me know what you think of it. I know Chris doesn't do anything without a lot of thought to the quality and comfort for the horse. And as someone here posted, he's not into a lot of "extra" when training horses. A good quality rope halter and lead rope with a popper on the end. That's all he uses, no carrot sticks ect....
Thanks to all that have responded, appreciate the input.
