I've only had my new boy for a few weeks now, but my quarter horse saddle doesn't come anywhere near fitting him. A trainer told me he needs close to a 9" gullet. I've looked online and have found 9" gullet saddles, but I would like to get more suggestions before I run right out and get one. I have a treeless I can try but haven't yet. Any suggestions on saddles for him would be helpful. I'm looking for a western saddle for trail riding.
