Please no lectures on bits not solving problems. I'm not trying to solve one, just enhance its use. I ride my TB in a french link snaffle. He's finally starting to use himself well and coming onto the bit nicely, but he never gets that nice wet foamy mouth, so I'm always wondering if there's more I can do to make the contact more inviting for him. The big Equine Affair is coming up this week. Yey horse shopping! I'll have access to pretty much every bit on the market. I like the french link, but am wondering if the type of metal it is made from makes any significant difference. Are there any types of metal or brands that would do more to stimulate his mouth? I looked at those happy mouth bits, but they're so fat. He's got a big fat tongue, so there's barely enough space for the bit in there.
