When doing flatwork, I ride my mare in a loose ring snaffle with a french link - she's fussy with bits and detests the nutcracker joint action. She goes well in it and seems comfortable enough.
However, when I go to jump, it's a different story. She tends to get so excited that she just races off around the course as fast as she can go. I understand that this is probably a schooling problem as well, and a change of bit won't work magic but it might help.
About a year or two ago, due to being completely unable to hold her in the snaffle to jump, I changed to a dutch gag for shows. I hoped that if I rode her in the snaffle at home, and jumped her in it at home, with lots of schooling I would eventually be able to go back to riding in the snaffle at shows, however that plan didn't really work out - if anything, she has grown and gotten a lot stronger over the past two years.
I really don't like riding in the gag, and Bella doesn't seem at all comfortable in it, but out of the bits I've tried it's the only one I can hold her in.
A friend mentioned the Waterford bit to me today, and how it stops the horse leaning - which is exactly what Bella does. But I've also read that it's useless in encouraging them to ride on the bit. I don't like the idea of getting her to go nicely on the bit in the snaffle at home, then go out to jump and have her ride like a giraffe, completely undermining all my flatwork schooling due to the bit.
Would it be worth a try? Or are there any other bits I could look into?
