I agree with most of the posts. It is imperative that first the saddle fits your horse, and puts you in the right position. Many of the saddles mentioned above did not fit my horse well. He is slightly short backed. Many would slip over his shoulder while riding, or flap in the back at the canter. I first worked with George from Canterbury farm (equation saddlery) in WI, do a custom saddle, sort of a schleese knockoff. It never fit my horse properly, and he was impossible to get out to the barn to fix or adjust. After a year I just wanted my money back. I had to invest in chiropractic, massage etc., as it was killing my horse. So much for Custom. He never returned my calls or the BBB, so it is now sitting collecting dust. So it is imperative that you find someone you trust and is reputable.
I don’t know where you are located but I had Ann from Equestrian imports come to my stable in IL- she is based out of Florida. www.equestrianimports.com. We ended up with an Albion that she did not have to make any adjustments to. After one year all is still well, horse going fabulously, and he is not hurting anymore.
