I currently have a Dover Circuit Elite (17', regular tree) for my paint gelding, and I don't believe it fits him correctly. Whenever I work him, and he 'sweats' alot; there are 'dry' spots on his back, underneath the saddle. And after I've been riding him for about 30-40 mintutes or so, he just wants to stop, and throw his head & whatnot.
While it is not a terrible saddle, I would prefer to get something of better quality that will last me a long time. I have a budget about about 2,000 at the max; cheaper is better. I don't show heavily on the A-circuit, more on the 'local' type circuit, and such. We jump; & he'll probably max out at about 3'-3'3ish, just depends.
Anyways, I think I would prefer to get a used, higher end saddle, rather than a brand-new. Lower-end saddle.
