Saddle fit is indeed confusing, and it is important. But you can't micromanage it. It isn't practical. Fit starts with the saddle tree, and even tree makers disagree on specifics. It only makes sense, if you have a wide backed horse, you need a wide angle saddle. If you have a narrow backed horse, you need a narrow angled saddle. If you have a short backed horse you need a shorter tree. It's hard, if not impossible to find a perfect fit, because the horses back is in motion whenever he's moving. a saddle that is too wide in the gullet, but has the proper angle, will sit too low in the front and throw the rider out of balance. I can give you a hundred scenarios, and I've seen every one. Most horses never complain, or if they do their riders don't understand what they're saying. Fit also depends on the skill; level of the rider. Someone who never collects their horse can use a closer fit in the middle of the back than someone who is rounding his horse to use his back end . The center of the back will lift from a 1/4" to 1/2" or more, so you need to build in a little bridging for the horse to round into. There is so much controversy on this, I'm still studying, trying to find the right answer. Dave is certainly knowledgable about saddle trees. He probably doesn't remember me, but I met him at a rest stop in Bowling Green, Ky, when I worked for Crates Leather, and have followed his career from a distance. I've talked with Len Brown, and though he's a little hard to follow with his scattered wording and strange capitalization, he has some good ideas. But a saddle should fit as least as good as we fit our shoes. Get as close as you can to the right angles, place the saddle so it interferes as little as possible with the shoulder movement, and helps keep the rider balanced. It stands to reason the rider needs to know when they are balanced. An effort at getting a decent fit is better than no effort at all. Saddlerlew
