Sorry I'm not 100% sure what you call this bit, will try and post a pic or a link. I normally ride both my 20 year old gelding and a younger horse in a jointed pelham. I normally use only the curb rein - yes I know it's not technically correct, but I never learned to ride with two reins and ride on a very loose rein. Reason for use of jointed pelham is no brakes on both of these horses. Y0unger horse is a cow horse and older one cow horse and my trail horse.
So today somebody I really respect as a horsewomen recommended me this bit. She says they use it on one of their endurance horses who also tends to get a bit hot and not have brakes. I would like to get away from the curb chains and especially on my trail horse use something a little different, for various reasons. http://bombers.co.za/sites/bombers.c..._Miles_lrg.jpg
I really hope this link works. Baically it is a three ring double jointed bit with copper rollers on the middle part and is made of sweet iron. Would it be a good change away from the jointed pelham?
