What kind of snaffle would work just like a kimberwick in terms of being able to have control of a h

I bought a 10yr old Haflinger Gelding and I rode him in a regular snaffle which gives me some control but not alot when he starts to act up I don't have as much control as I want to. I do dressage and its not legal to use a curb/kimberwick unless you're third level using a double bridle. So if anyones has any ideas or comments that would be great.

thanks

A snaffle cannot work the same as a kimberwick as a kimberwick has leverage. The action is different, the leverage bit give pressure under the chin, and a different sensation in their mouth, applying some pressure to their palate, tongue and bars of their mouth. A plain snaffle of any sort applies pressure to the gums and bars of the mouth, and does not work off the tongue or palate, or with pressure under their chin.

If you are needing a bit of extra control in a snaffle bit, then you have to look at your options. You can go to a narrower bar, that makes the pressure narrower and therefore somewhat more sharp. You could try a slow twist to school in, but you need to be very aware what you are allowed to show in legally. You could try a french link or other 3 joint type of snaffle, if it is legal for your dressage classes. Obviously experimently with the sides as compared to a D-ring (My trainer doesn't like much) and O-ring (supposed to have a bit more feel and warning) a full cheek (good lateral movement) or an egg-but to see what your horse responds to the best. Obviously, borrowing from a friend is a good idea until you have a chance to see how your horse responds to one or the other. I have found that minor differences can make a huge change in some horses. Two bits that look very similiar to our eyes can ride differently in a horse's mouth, so sometimes one brand will suit a certain horse better than another, just due to the exact why the bit bends in the middle, the thickness of the bar, the shape and bend of the bar, etc.
