Sorry for the novel.
A little bit of background here. This horse is a 28 year old Appendix QH chestnut gelding in use as a hunt seat lesson horse for many years, before my riding teacher got him he was used to give jumping lessons 8 hours a day. This usage led to him having navicular disease, for which he is properly shod (from vet X-rays working with the farrier). He is no longer used for jumping. Everyone else rides him in a three-piece lozenge snaffle eggbutt.
I ride him in a double bridle. My bits are the Fager Weymouth Victoria Mullen mouth curb (no longer made) 135mm wide, the mouthpiece is around 12mm thick, and the shanks are 70mm. The bradoon is the Fager Alice, 125 mm three piece snaffle with fixed cheeks which has a titanium roller in the middle of the mouthpiece. I altered a Micklem multi-bridle by cutting off the chin strap and I run the bradoon hanger over the crown piece through the loops of the browband. The horse and my riding teacher are happy with this double bridle, in fact when I suggest going back to the snaffle my riding teacher says–no because she likes how he moves under me. I ride Forward Seat ala Vladimir Littauer’s “Common Sense Horsemanship” in a Pegasus Butterfly Claudia jumping saddle. I have been using the double bridle on him for around 2 years with no fussing or head slinging or any other problems. He obeys my light hands, used in coordination with my lower legs, well. His face does NOT go behind the vertical.
A few weeks ago I was sort of bored during my “homework ride” and decided to see how he would do extending his walking stride when I just kept contact with the curb bit, I sort of tied the buckle end of the bradoon reins to the grab strap making sure the drape of the bradoon reins was inside the curb reins. Taking a light contact with just the curb rein I alternated my lower legs to ask him to extend his walk. He not only extended his walk he reached out for the bit with a relaxed mouth and when he wanted more rein he slid the “notched” curb reins through my relaxed fingers. I showed my riding teacher this my next lesson and she was impressed. Several rides later I did this at the posting trot during a lesson with the same result, he extended his head and neck, his back felt like it lengthened, and his whole body relaxed. Usually when he goes from the trot to the walk sitting down on his back feels like sitting on a jackhammer down, today his back felt nice, soft, swinging and fluid.
I get BETTER extensions of his stride at the walk and trot when I have contact with just the curb rein than when I have contact with just the bradoon rein. He relaxes, reaches his head forward and down a little, nose most definitely leading, and extends his stride without a lot of extra leg on my part, in fact I have to use LESS leg than when I ask him to extend his stride when my contact is mainly with the bradoon. He is light in hand, he “talks” to me with his tongue moving the bits some (no froth). My riding teacher tells me he is showing no distress and that he looks more relaxed than when I keep contact with just the bradoon.
Has anyone else had this type of result from keeping contact with just the curb bit?
I was NOT expecting this result, my riding teacher was not expecting this result, but this ancient lesson horse thinks that contact with just the curb bit is better for extending his stride although my hands are sort of compromised with my MS (which is why I keep contact with relaxed and sort of loose fingers.)
At the end of my lesson today my riding teacher wanted me up in two-point for a while. I got up into two-point at the walk, legged him into contact with the curb bit, and this ancient horse who prefers the lesson horse 2 MPH walk gave me a GOOD flat-footed walk like what was our ideal walk back 50 years ago, at about 4 MPH, all with contact just with the Mullen mouth Weymouth curb.
