Background:
My mare is fairly competitive, especially when she is great shape. I have the most issues slowing her down to a sane pace when we are on conditioning rides( about 1/2 the time with her pasture buddies, who do fast LDs. We do midpack 50s and multidays) when she will get very competitive. I currently use a 3 piece snaffle that she will listen to ( eventually), but I do not like to have to pull hard on her, which I do have to do when she really gets going. During an endurance ride, she is generally pretty calm and relaxed - 1st 5 miles occasionally have some idiot moments but they are decreasing. During the 2nd half of a 50 or on multidays, I often ride her with a rope halter if the trail is not overly technical. We do some low level dressage work and she is very well behaved solo or with a small group of non-competitive horses out on the trail. I can slow her down/ get her to focus with some low level dressage movement ( yielding, shoulder in, etc) on the trail, but I ride on alot of narrow trails where that would not be a great idea.
My question:
Would it make sense to try her in a sightly stronger bit - currently thinking a short shank snaffle ? I think that it could (hopefully) , get the message across to her without me having to yank on her mouth.
Any advice would be welcome
