Would one of these help with my horse? Took him on a 10 mile fun ride yesterday, did loads of cantering - he wasn't strong, and came back to me easily, so I don't need more brakes, but when cantering he puts his head right down and leans, even when we're going slowly. He's in a hanging cheek French link, we jump and do dressage in it, but yesterday his nose was almost on the floor and I worry that if he stumbled or decided to buck I'd be in a vulnerable position.
I could stop him by going into a nice, round, steady trot then asking for canter, but as we went into stubble field after stubble field it wsn't that easy to organise myself as loads of horses cantered past, so often he had his head down as we set off into canter, then it's really hard to get it back up.
He gets his tongue over a pelham, so I wondered if a 3 ring version of the mouthpiece he's in would help (I'm happy to use 2 reins). It would only be for fast hacking as his flatwork canter is fine.
