I'm having issues fitting my new OTTB with a saddle. He has a typical thoroughbred shape - very pronounced withers, but also well-muscled shoulders. My current saddle is a Beval BZ Natural with a medium tree. It's not terrible, but I'm really picky about saddle fit and it seems like it's too wide for his withers, but too narrow for his shoulders.
Does anyone else have this problem? If so, how do you fix it? Ideally, I'd have a custom saddle made for him, but that's not in my budget. I normally don't like fixing saddle fit issues with pads, but it seems like that might be my only option for now.
