I’m a re-rider and I’m riding 2 horses at a friend’s barn. One is a big boy warmblood and the other is an OTTB with high withers. The AP saddle she has for the OTTB isn’t great and I’d like to get my own. Is there a unicorn saddle I can buy and use on both horses (and any future ones she brings in)? I’m out of the loop bc I haven’t seriously ridden since the 90s.
