I've heard a lot of good things about Circuits. My lease horse (I need my own tack) is an extra wide. But I am not sure if the lease will continue after the summer so I don't want to have to sell the saddle and buy another again if I ride a different horse. Is the Rotate to Fit gullet system for Dover relatively new? I saw it in my new catalog but can't seem to find it on their website. Anybody have one of these saddles? Or can recommend another saddle with interchangeable gullets? Thanks.
