I agree with you complelty (sp?). I do use a tie down on my horse, but it does not keep his head to his chest it just keeps him from his bad habit of tossing his head and breaking my jaw. Also when I got him he would not go right and every time we tried he would throw his head real high.
But to get him to flex right we never tied his head to his saddle, that is just horrible.
+ his tie down will be out of use in no time at all. It is a loose tie down and he does prove he can still use his head! I don't think you are thinking anything wrong, tell somebody. :)
