Those are tie downs, not a german martingale MR.
I personally only have used a GM on horses that get a little too light on the forehand, as GMs tend to force the horse on the forehand. So I have used them on problem horses who want to rear. If I feel them get light, I bring them down while forcing them forward. For training a barrel horse, I wouldn't use a GM. You want a barrel horse using his hind end, not his front

Now I don't use a tie down on this particular horse, but if he begins throwing his head or hopping his front end up in the future around the barrel; would you suggest using a tie down or a martingale to help that problem? My mare did this before I gave her time off, now I don't know how she is.
