While he has worked well in it, I have done more research and haven't found much information supporting the claims of this being a mild bit. In fact, I've found a lot of information saying it is overly harsh.
For no particular reason, other than feeling like some change, I put him in his loose ring snaffle he was started in recently. Other than needing more reminders to stay collected, he has worked extremely well in it. I don't feel he needs to be in a Tom Thumb if he works well in his baby snaffle, but I do like a shank because he is gaited and it's much easier to keep him collected in a short shank.
I am looking to switch him into another bit, but my old trainer said anything other than the Tom Thumb would be harsh.. After some research on mouth pieces, I am thinking of looking into a French Link mouth piece, with a short swept back shank like his current one.
I chose the french link over the solid mouth piece because at one point, another trainer put my mother's horse's bit in his mouth, a similar shank length and sweep, but with a solid mouth piece. He FREAKED OUT. So a solid mouth piece is out of the question.
My issue is, I do not know the name of the bit I am looking for? I would like to compare his current bit to bits in store to get my measurements, and then purchase a bit online because I am a college student on a budget. I have tried to search ebay, but don't know the 'name' of this bit.
What would I search to find a French-link mouth piece short shank bit? Like this
