I now use the level 1 myler snaffle o-ring bit with the comfort barrel...I like it because all three of my horses are pretty green, and the barrel in the middle really helps me direct them but without any pinching...I also got the sweet iron for them so yes they do drool, which is good. Its not a harsh bit, in fact Id be surprised if it would be able to do any damage to their mouths, which is what they need because I don't want them to have a bad experience with a bit. Unfortunetly the trainer I sent Cochise to actually started him in a twisted wire snaffle, which wouldnt be bad if he didnt have a time with him bending right, which eventually cut into the side of his mouth. The trainer said it wasnt bad, he put stuff on it but would help him remember to bend...but for cochise it did the opposite...I had a hell of a time putting my myler in his mouth because all he could remember was that bite of the other one I think. I also used a hackamore when I got him home until his mouth healed ( I know some would say babying the horse..but I wouldnt find riding enjoyable if my mouth hurt). It has taken a couple months plus lots of bending and flexing with the myler to make him realize there is no bite to the bit (he also wanted to buck when I would bend to that side, I had to be really patient). I know that myler has a large line of bits, but I also realize that if you don't know how to use them its best to stick to the basics. I first tried the myler ( I bought a few of the cheap ones and didnt like them) when my other two got back from their trainer (different one that Cochises), he used a myler o-ring snaffle and said it may be more expensive but he would by 2-3 cheaper bits to the one snaffle due to using it daily. I also like the way they ensure there is a curve to the bit to fit the horses mouth better.
