I have tried a TT and, while my horse didn't have a problem with it (I can ride him in just about anything), I hated the lack
of feel that it had. There was no subtlety with it, no nuances to my cues, it was all very blunt and rigid. I can compare it to trying to put in stitches with a sharp stick and kite string. You might get the job done if you really
know what you're doing, but it won't be pretty.
I greatly value the amount of feel my horses have and I expect a great deal from them. While the bits that I generally use aren't those big, expensive, custom jobs that some do, I make sure that the mechanics of my bits are suitable to the horses that I ride and the goals that I set for them.
This is strictly a personal preferance, but I thoroughly dislike bits that have shanks and a broken "snaffle" mouth, just because I don't like the feel of them. I much prefer a good ported curb, either solid or with a barrel. I like being able to pick up one
rein to fine tune a movement without the entire bit collapsing on the horse's face.
Here are some good, inexpensive bits that are much more suitable for a horse's first experience with a curb bit than a TT could ever hope to be.... 254330- Partrade Black Satin Bit Saddles Tack Horse Supplies - ChickSaddlery.com Reiner WIde Port Swivel Shank Bit Saddles Tack Horse Supplies - ChickSaddlery.com Kelly Copper Inlay Arch Mouth Bit 5" 239091- Partrade Cowboy Collection Short Slotted Futurity Bit 796- Reinsman 7" Steel Reiner Billy Allen Mouth
This one is really mild because the shanks are about as short as I've ever found on a curb bit. Saddles Tack Horse Supplies - ChickSaddlery.com Francois Gauthier Antique Hinged Futurity Bit
