I like the Pro Jump better than the 500 caramel color cc. Pro Jump is a little more forward flap. I thought the seat was hard, though. It also runs big, so I fixed both probs with a custom made leather bump pad from Winners' Circle.
Of the ccs, Collegiate Convertibles, Wintec 500, Pro Jump, and Bates Caprilli are all the same tree and same gullets.
There is an Ashley & Clark Ayr cc that has a Sherwood changeable gullet tree $1500 or so but it's a great saddle, better than the Collegiates by far. You can order different flap width & length. See my thread at Horse Grooming Forum or Google for Ashley Clarke Ayr and you'll find it. I posted pics of the gullet and how it attaches.
