He's in an eggbutt snaffle (1 joint). We discussed trying a running martingale on him. I'm hesitant to do so, because my experience has been that a running martingale messes up the line to the mouth even more. I will not use a standing martingale at all for safety reasons.
Here's what I'd like to try.
-1- I'm thinking he might be raising his head to get away from the snaffle's nut-cracker effect, so I though I'd try an eggbutt french-link snaffle.
-2- Lots of roundpen work to work both lateral and vertical neck flexion to try to get him to loosen up and drop his head.
Am I on the right track? Any other suggestions?
