OK so I have a 2 1/2 yr old paso fino who hates his snaffle. He's mouthy, unresponsive, head tossing, the works. Is there anything I can get him that's not harsh because he's still learning? I'm afraid a Mullen mouth would be too soft, but a kimberwick is way too harsh. Someone suggested a french link. I've never had one so I don't know. I have a curb which he likes but I don't need the leverage. Suggestions????
