Would this bit be good for my OTTB?

I have that exact bit for my very green TB and she loves it. She accepts it nicely and loves the copper mouthpiece. It is very soft and considering most TBs have soft mouths, I think it will work well for your horse to. Plus it doesn't hit the roof of their mouth which is something I always look for in a bit. Hope I helped!

That's a pretty mild bit. I'd start out in a regular snaffle first, as that or a ring bit(which is a snaffle with a thin ring attached to it), is almost certainly all he's ever worn. See how he responds in the bit he's use to and then go from there. If you're very fortunate and he still has some sensitivity left in his mouth you could sure try him with the bit you're looking at. If he's hard mouthed you may want to go in a different direction, so it's best to evaluate him first before you go spending a lot of money on equipment that may not be what he needs.

i dont know if i would use copper. you may find the horse already "plays" with the bit enough. many ottb's put their tonge over the bit, or suck their toungues during times that they think are stressful. i would use a 3 jointed bit like a dr. bristol or french snaffle.

you will find when you start riding him that he has no mouth...and probably does not steer very well. the 3 joints work well for a "dead" mouth, and they are still gentle, in soft hands.

you can always upgrade to a copper bit, if he just wont soften in the mouth...

i hope you like flat work....cause it is going to take a while before he is anywhere near ready to start jumping under saddle.

if he is just brand new yesterday off the track i would start him in a simple snaffle nothing complicated but before you start jumping you are probably going to have to put a lot of work into gaining his trust, working in an arena, finding a balance. your flat work is 90% of your jumping so it matters alot. if he thinks he can run in the arena with you on him then whats he gonna do at the jumps? slow down? most likely not. if he starts running after and before the jumps towards them not only does it make it sloppy it turns it into a horrible habit. even if you wanna do jumpers he'll be knocking down fences and resale will be hard.

calm him down, let him get used to the new kind of work you will be doing with him and take it slow let him know theres no rush anymore low gymnastics are great work too and so are poles but the bit sounds pretty good too and you will really never know until you get on him and even then it might change have fun and congrats on your horse

That would be the bit I would suggest. The copper tastes sweet to him so he'll more willingly accept it. While the loose ring and double broken part make it hard to go back to race mentality. Race horses are trained that stead pressure on the mouth means to go. The harder the pressure, the faster they run. A single broken, full cheek, or curb would be disastrous.

i would suggest just a snaffle or if he hates the idear u can use a rubber loose ring but it depends on him really

He should begin jumping in whatever bit he's using now.

That bit looks okay, but why buy a new one until you find he needs it?

just start with a snaffle. no need to get particular bits until you know him well.
