I have a bit nearly identical to that one in my tack room and it is a true 5". Judging from the way it looks on him, you'd need a 6" at most, though I'd try a 5.5" on him first because they're easier to find.
Oh, and just for grins and giggles, I put that FG futurity bit on Rafe today. It's snug for my taste (corner of his mouth is right at the shank with no space), but it will work for the time being until I can afford a custom 6". I've got a few pictures but I'm not on my computer where I can upload them. I'll get them later on tonight.
Thank you for the replies! I don't know what his previous owners used and I don't know much about bits. I thought if it was split in the center....that meant snaffle. What is a good online place to purchase these bits??
I do belive you are correct. I used to think differently and I found some info that said it is a snaffle but that may depend on where you put the reins. I can't remember for sure
In theory you can connect the reins to the hole the mouthpiece attaches to, and effectively have a snaffle bit (in this case, a french link with roller):
I tried it like that on Mia...she treated it like any other snaffle: for advice only. But it would give a true 1:1 ratio of pressure on the reins to pressure in the mouth.
There was a question earlier about rollers...Mia really seems to like having something like a roller or rings in her mouth to play with. When she gets a little nervous, I'll hear her playing with the roller, and it seems to help her relax. That is just one data point, but it is one instance of a horse acting calmer with a roller. Trooper, OTOH, would probably melt if he got any calmer than he is in a single joint snaffle (or double joint, or curb, or bitless, or most anything else you care to put up there). Although he MIGHT protest at the OP's original bit!
Just because I'm super excited about it, I found the bit that smrobs posted (the FG Futurity bit) at my local CAL Ranch store for $50! Even though it's on sale at Chick's for $35, once you add shipping, it's almost the same price. Posted via Mobile Device
