I have been trying to find a saddle to fit my young horse for several months. I’ve tried what seems like dozens and they all slide forward and interfere with her shoulder while on the longe. I’ve tried wider trees, narrower trees, flat with minimal curve, gaited saddles, etc etc ad nauseum. The best I’ve found is an Arab tree with a 7" gullet but it still slides forward. I can probably make it work but I’m not in love with it. It’s a circle Y and just seems cheaply made.
What do I try next? A pro fitter? I’ve never had so much trouble fitting a saddle before. I want to ride my horse dang it! If you have any nuggets of wisdom or want to commiserate, please do. Venting over.
