Would a chain mouthpiece be considered harsh? Is it sort of the western equivalent of a Waterford?
My gelding does have a short, thick neck that ties in slightly low. Part of his reluctance to ride on contact is his initial training, but part of it in my opinion is also his conformation. Interestingly, he has more definition between his chest/neck now after a winter of mostly dressage work.
He is the most one sided horse I’ve ever ridden, and I’ve ridden several OTTBs who were definitely left sided. I like Jane Savoie’s exercise for that (ride the “good” direction counterbent, and the “bad” direction over bent). It has helped, as well as shoulder in. I also like an exercise from one of Stacy Westfall’s videos, where you ride a figure 8 without changing the bend the entire time. It’s super easy on his “good” side but very hard on his bad side. Very helpful though. When neck reining he stays straight from nose to tail. He doesn’t seem to get confused going from dressage in a snaffle to neck reining on a drapey rein in a curb, but he does exhibit a preference for the draped rein. I just want something that I can warm up in two handed, or switch to two handed during schooling without feeling like I’m sending too strong of a signal and risking dulling him. With the robart bit, I can bridge the reins and get him to bend, but when I go back to neck reining/one handed, he’s straight as an arrow again (except when he gets tired loping, he will cant himself towards the rail, but I think that’s just an artifact from his time in the show ring).
I’m looking at the Billy Allen bits, or the myler type with a low to medium port. He does seem to prefer some degree of port (I have a very low port Pelham and a medium ported polo Pelham and he definitely prefers the polo version). I’d also like to try a sliding cheek/gag bit but I haven’t found a mouthpiece that I like yet on one. They seem to be marketed toward the barrel racing crowd and I don’t need a mouthpiece with that much bite. We have power steering and excellent brakes.
