So that's why I want her in the snaffle, because this is the only bit she hasn't posed ANY resistance to.
That almost sounds like my guy when I got him, he HATED all bits and even still does a little bit of a head toss. I went back to basics with him and worked on his bitting, using a nice comfy doubled jointed bit (Sprenger RS). It took quite a few months of patience patience patience but in the end it was worth it. He now accepts the bit, bit contact and is now very light with it.
Your horse may not go in a snaffle now, but I'm sure that with a few months of work she may go much better. And I agree with checking for mouth issues first.
One thing to remember that I tell people who are planning on switching bits around to fix something is this - Different bits communicate with the horse in different ways. Going from a curb to a snaffle, or a snaffle to a curb is like suddenly speaking to your horse in a completely different language. If someone suddenly started speaking to you in Cambodian, or French you probably wouldn't understand the first day, or even the first week. You might start picking it up eventually after time and patience. So, when you switch bits, you can't depend on the reaction of the first ride to decide whether or not that bit works for the horse.
