Hahahaa if he wasn't unregistered I would look at finding a nice proven tall TB broodmare and breeding to him for a taller half-sibling to miss Satin... he is lovely, his get are all lovely, seems to breed a very consistent [very nice!] type... but any of his foals will only be eligible for colour registration and that's if they're lucky.
And the other thing is he's thrown palomino which I'm not a fan of - if I was guaranteed to have bay, buckskin, black or smokey black I think I would breed to him tomorrow regardless of registration. I love the cob types, and I believe a good grade is an excellent horse. But breeding to him would be for a keeper, not a sale pony, and I'm looking at training up an OTTB sometime in the next few years. I don't need a greenie AND a foal.
