If this is the case with your horse, there are a bunch of different options. You can use a lower port, a broken mouthpiece in the middle, a solid mouthpiece, a medium port. It all depends on what your horse is used to. I've heard some people say that you should switch to a stronger mouthpiece for a few days to get the horse to respect the bit. I've never done that before and have no experience with it whatsoever. But please, always ask someone whose more experienced than you. Some horses just don't go good in kimberwicks because of the chain action. I don't like kimberwicks, I like kimberwick uxeters.
could you recomend some specific bits? I don't have a jointed kimberwicke or one with rein slots, and my trainer suggested a stronger bit for field/trail work. This horse has a full cheek sow twist dr. Bristol for riding in the ring, a D ring slow twist for random stuff like polo x and whatnot, and has a kimberwicke for field trail work, but being a retired racer, he will take advantage of my strength when he wants to go, so I don't ride him in anything less than a slow twist bit. After he took off with me multiple at full gallop and I couldnt stop or slow him (we were in the middle of a bean field and incredibly dangerous) my trainer let me borrow a rubber jointed pelham, and it was better, but not quite enough so we went to the kimberwicke we have now with no rein slots. So if you could recommend a few or send some pictures of bits you think I should try, that would be great. My friend suggested I try a oval gag with the rope that attaches to the crownpiece.
