Baucher bit, single joint or double joint?
I am starting an older horse and working on getting him to accept contact with an outside rein. He gets it but is not consistent. He tends to elevate his head as a response (part of that is his conformation, he is an Arab/Trakhener and tends to be uphill).
He doesn't stiffen his back like a giraffe, he doesn't release at his poll as much as I'd like.
After a lesson, my instructor suggested trying a Baucher bit on him. He goes now in a O-ring and D-ring double jointed bit with a oval "peanut."
Should I stick with a double jointed or is there a reason with a Baucher to use the single? He is very quiet and sensitive so has always been fine in his double-jointed snaffle. I am leaning toward a happy mouth either way and have found both options.
