Hi guys! I currently ride in a 16.5 inch collegiate senior event saddle. (it has a deepish-seat) and my horses old owner is selling her old custom county jumping saddle made for him. It's a 15 1/2. My current saddle barley fits me, but these two saddles are totally diff shapes, county flap is more forward, seat is shallower. I'm 5'3. I've always wanted a county saddle, so if the price is right I would LOVE to have this one. Concerned about fit. Not sure.. what do you guys think???
