My 17yo friend who is half-leasing my mare wanted to get an english saddle to use with her on occasion, so we did a wither tracing and sent it to Trumbull Mountain to get their opinion. After evaluating the tracing and pictures we submitted, one of the people from Trumbull said: Sierra is quite broad in the shoulder and mid back. I feel she would do best with a saddle that is laterally broad with a full front gusset and she is on the hoop tree cusp. I asked about hoop trees because I'm unfamiliar with them, and he said that a hoop tree saddle has a more rounded, broader pommel arch versus a more angular one and that they allow a saddle to drape more around a horse instead of perching. He mentioned Thorowgood as a brand that offers a saddle with a more rounded, broader pommel arch (it's their T4 line) but I am sure there are others. Does anyone have another brand or specific style of saddle they'd recommend for a horse with a broad shoulder and mid-back?
