Has anyone ever used a Buxton martingale on a miniature, like they use on the standbred? It looks to me like it would be a good training tool. If you fastened the Buxton to a surgical, then it could be used for long reining. Then I could fasten pvc shaves to the surigual to act like shaves. That way I wouldn't have to buy a team harness until I am sure of the size of the team.
