My dd's pony is at working livery. She is lovely but can be a bit of a handful. With inexperienced riders who are at all heavy handed she is inclined to head toss. If she has a light handed rider she's fine, and if they aren't, a running martingale sorts it out.
When we went up today, she was wearing a standing martingale, and the teacher said she had been tossing her head a lot, sot they were trying it out. I hate standing martingales - I think they are too restrictive, and could be dangerous, but I'm not sure enough of my ground to ask them not to use it without some research. So waht do you knowledgable people think? Am I being PFH about this?
