Thanks for the feedback Brenna!
I love shoulder relief girths because they allow you to place the saddle further back while the girth can still sit in the middle of their girth. This allows for more shoulder movement, making it easier for the horse to lift and stretch their shoulders.
Thanks Rebecca. It does seem like a good solution.
I personally love the shoulder relief girth. It really helped my horse balance and use is shoulders and helped his flying changes.
