I warned you I had some horse stuff coming and here’s one of them.
These MUCH improved bridles are listed as “works in progress” but I have them in my game and I’ve had no issues with them. You can see a shot of Hunt seat version on my Tucker’s Fool post.
These bridles come in two flavors: Hunt seat and a Western shank. There are several style of both and you can pick what you want.
