Anybody have any experience with Allegany Mountain Trail Saddles? My Tennessee Walker has a very broad back and low, wide withers. I have been looking to purchase a custom saddle so as to ensure a good fit for him. The Allegany Saddle Co. Seems to have a very good fitting procedure. I am particularly interested in their "Cascade Wade" model which has an extra wide tree that might be a good fit for my horse. Thanks in advance for your replies to this post.
