In particular have you tried the combination bits?

Some might recall I have a work in progress otherwise known as Lucy. She's a 5yr old QH mare with a fiesty temperament, particularly when it comes to reining/bitting. She is extremely light/sensitive. The biggest issue was turning left. If she didn't want to she would run sideways or backwards, toss her head, and sometimes buck and rear. I was torn as to whether to sell her or try to fix it. In the end, with a lot of input from the DH, the decision was made to keep her as she does have some redeeming qualities
We made several changes. Firstly, no more dry arena work period. My husband often takes her to brand and move cattle, I mostly trail ride her. I give him a hard time that he's spoiled my horse, all she wants to do is work and she has little time for my trivial activities
We forgot about bits entirely and got her a Jim Warner hackamore. She has not had one of her episodes in it (about three months now). We had her teeth floated in April/May. According to the vet they were not good. She also has unusual teeth in that she has canines, which he'd never seen in a mare before.
I gave her two months to get used to her 'new' teeth, then tried her in a D-ring fixed snaffle that she had previously got along with best. I stayed in the arena which may have caused a lot of the problems. She was very fresh that day, and had no 'whoa' whatsoever, which had never been a problem before. She kept trying to run off with me to the 'out' gate (not back to the barn!). The more I tried to stop her the faster she would go. A one rein stop almost got me dumped. She would not back up but ran sideways throwing her head instead. I switched out bridles and she was just as bad in the Jim Warner. Maybe that's a good thing - she was in a fiesty mood, not mad at the bit? Logic told me that I should have thrown the gate open and gone somewhere; fear/self preservation told me to get off.
Since that day we've stuck to the hackamore, and she's been good. It seems to help her (and I!) if I give her something to think about when she gets tense. She can get high headed and a little too alert on the trail, but if I find an obstacle for us to tackle she immediately drops her head and relaxes. I helped my husband practice roping by holding the herd and i'd never felt her more relaxed. A calf flipped over end and landed right next to us, and she didn't even blink.
Next month Lucy and I are going to a ranch horse versatility clinic. I'm excited, but very anxious too as it's her first time away from home. My old trusty horse will be coming as backup. We have hit a bump in the road though... the NVRHA do not allow mechanical hackamores. I can ride her in a snaffle bit until January, then she has to be in a curb bit.
So back to the original question! It seems that the combination Myler bits use nose pressure. I'm wondering if that might be more acceptable to her and whether they have worked for anyone on their horses. The pricing is horrible!
