Walkers is on the hunt for a gaited horse saddle. Any ideas?

I want to try the W.O.W. saddle. It has an adjustable tree and component structure. My osteopathic vet wants to look closely at it for the endurance riders. So far, I'm having trouble locating a U.S. rep for it. Suggestions?

My current custom is made by Centaur saddles. Still tweaking the blocks on this one. The memory foam seat is a new design and does a super job of not making the nerves in my back and legs light up. First seat that doesn't hurt.
