Well, sorry to say, join the club. I also have a hard to fit horse that
sounds a lot like yours. I wouldn't even consider the aussie for him but did
try a lot of other including Ortho Flex and SportsSaddle. Katee Owens of
Advantage Saddles is custom making a saddle for my guy. She has a great demo
program so you can try the saddle before you order one. She also has a web
page Click here: The Advantage Endurance Saddle Check it out.
I wish you luck in finding a saddle that will fit. I am anxiously awaiting
mine.
