Saddle suggestion for a gaited horse
 

I just bought a new TW. He is small framed and a little bit sway back. I would like a new saddle for him. I also have a larger broader TW that I wish I could use the saddle on too but I am assuming because of the size difference it won't work. Does anyone have any great gaited horse saddle suggestions? I can spend up to $1,500 but would really like to spend much less so I can buy them both one if possible!
