After graduating from his snaffle, my trainer put my horse into a Tom Thumb. I didn't know much about bits at the time, and assumed that the Tom Thumb was normal, and was told it is not harsh because it is broken with short shanks. He has done very well in it, and has shown no signs of pain.
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
