By any chance, are you trail riding in this bit?
I think I'd asked the trainer, it an inquisitive manner, why he chose this bit.
He might have a good answer and I hope he does as I'm not one to by into all the hype surrounding bits.
Use what works....
I was about to say the same thing. Ask the trainer why
they believe this is the best bit for your horse. Ask if they ever use other bits, or if there ever comes a time when they believe a horse has "outgrown" the need for the double twisted wire and is able to move into something less severe.
I do think it's odd that a trainer uses the same (type of) bit on every horse they have in training. Not only that, but a fairly severe bit.
You can tell a lot about a person (especially someone who is a "professional" in their field) by their reaction to being asked for an explanation of why they use certain bits, equipment, etc.
Some of them really fly off the handle and get defensive, dismiss your "questions" as some kind of personal attack, and offer no actual answers.
They may be condescending, saying that they're the trainer and they know more than you so if you're not satisfied you can take your horse somewhere else.
Those are the ones you probably want to stay away from, because it's likely they know far less than they want you to think they know. They don't like being asked questions they don't know the answers to, or being questioned at all. . .they think that being the trainer = always being "right."
As for the bit making
the horse gait better. . .sorry, but I'm not buying that one.
