Haflinger?

I have a soon-to-be 13 year old haflinger mare. She is truly a good girl, but I don't know what classes to put her in. She doesn't move like a hunter but could get along fine in very small shows, but I would like to enter several show series, not just two. She wouldn't be good for eq because she is a bit rushy and needs a firm hand with changes in body and hand position. That is out of the question, but should be ok for very small shows. But the big issue is her lips.
Yes, lips. Opposable lips.
When I ride her (and even put pressure on her nose with my hand) her lips just go and go and go. They form words, but no sound comes out. I think I would get marked down right off the bat because of that.
She also chomps at the bit.
So that leaves jumpers. She is pretty fast and can collect her canter a bit, but im worried about sharp turns because she sort of drifts.
What do you think?
Thanks for the input! I'm desperate!

She jumps at least 2 feet

What kind of bit mouth piece do you use? Maybe a different type of metal (sweet iron, copper inlay, etc) or different type (french link vs si glen jointed or arched mullen mouth) would help keep her mouth more quiet?

It's not really in our budget to try bits, I should have mentioned that, but he uses a dee ring snaffle with copper rollers, very plain. We have tried just plain snaffle, but she didn't go as well. I have a quarter moon/ half moon whatever bit for my other horse that we are trying, but we need to poke another hole or two in the bridle because it fits differently than the dee. We have considered a happy mouth just so it didn't clank so much, but just don't have the budget for it. What if we get it and it doesn't work? We really don't need another bit! Have too many that don't fit our horses! Lol...

If you want to fix this it is going to include experimentation with bits , my haffy needs a very plain bit to have a quite closed mouth and she does dressage in a myler snaffle (the shapesuites her mouth) and hunting in a kimblewick.

Can you not show her as a haflinger breed class? Or just do jumping competitions.

You don't have to buy bits to try them. Have anyone you can borrow from? Buy used and sell if they don't work? Several cheap/free options to find what works.

I would check how the bridle fits first-- had a mare the would chomp when her headstall was loose.. also check how much pressure you're putting on her mouth.. and see if she might need her teeth done..

With all do respect-- if you can't afford the proper mouth care, or bit for your horse, you probably shouldnt be showing that horse. Its a very important thing to get correct.

Clava :
No haffy breed classes in our area-i checked, and not many lower level jumper shows :(
Toto:
Bridle fits, teeth floated regularly, no oral problems, she has a beautiful mouth. She chomps with or without pressure, mostly standing still or walking. Lips go nuts at all gaits and even without a rider!

No Haffy breed classes in my area either, the UK only really has one big show (too far away for me) or foreign breed classes If I were to show my haffy it would be in foreign or as a working hunter (not the same as US hunter classes). But there are always low level jumping in most local shows. Hope you find somethig to do.

Smartpak has a great return program as does http://www.dressageextensions.com/

Apparently you can try it for $15 and then if you purchase it the $15 goes towards it? Or something?

Then how is it in your budget to show? You can buy several good bits for the cost of entering a single show, not to mention borrowing from friends, or buying from somewhere with a good return policy.
