It seems like a solution waiting for a problem. I think most people that have problems with thier bit pinching actually just have very poor use of thier hands. I have used the same two loose ring snaffles on every young horse I've ridden in the last 15 years and have had very few problems.
There's nothing like the Rockies in the springtime... Nothing like the freedom in the air... And there ain't nothing better than draggin calves to the fire and there's nothing like the smell of burning hair. -Brenn Hill
