I had great luck with fit on my wide back horse
with the Arabian Saddle Company Solstice. It had a tad more of a dressage leg
position than I was used to, so it did not work for me, but worked for the horse
great. The panels cover more surface area than many English saddles, so it
distributes the riders weight well, which is nice for riders who like me, are
not "lightweights". You can find them used for under $1000. Great quality
saddles. Contact Beverly Grey, and see if she knows of any used ones
available.
