I have a 5 yr old mare who likes this bit http://www.smartpakequine.com/jp-kor...x?cm_vc=Search , covered in latex tape. I covered it for a young filly just learning to wear a bit who tended to bang her teeth when taking the bit out, who actually didn't like wearing this one anyways, and to save time one day tried it on the 5 yr old who did like it quite a lot. So, my question is; what bit could I use that might be similar to this one covered in latex for her. I worry the 3 piece happy mouth has sharp edges, uncovered she is a little shier about her contact, she likes the bumpy happy mouth, not the straight bar and she hates the rubber dog bone (makes her suck her tongue). I do not want to spend a bunch on a test bit so suggestions that lean toward under $40 would be awesome!
