I know Simco fits my mare, but I may consider other brands of quality older western saddles. MUST have an 7.5 or 8 inch gullet, and would prefer to see more of a u-shaped gullet than a-frame. My mare has HUGE shoulders. I need a 16 inch seat, would prefer square skirted, but will consider round as well. Just looking for something to school in and trail ride. Budget is around $300, can't go much over that.
