That's a very mild shanked bit and it's not a Tom Thumb but I think it's called tear drop shanked bit. Your horse really should be neck reined in it otherwise go back a step and get him into a simple snaffle. It can be a "D" ring, an "O" ring, or a full cheek.
Once you have your horse neck reining then you can move into the bit you are using or just ride him in the snaffle.
Gaited horses are usually worked in a shanked bit and they will gait better if they are collected a little with some light contact rather then a loose rein.
I'm not arguing with you, I'm just explaining why I'm right.
Nothing sucks more than that moment during an argument when you realize you're wrong.
It's not always what you say but what they hear.
