Although you can never forget the 50% that the mare contributes to the equation, I have never heard of nor seen any "kooky" Popeye K foals (and I happen to know many). Further, they do not look for a "nice flat jump" in the hunter ring. I'm not sure where you have ever heard that but it is entirely incorrect. Hunters should have a nice rounded jump which is called the bascule http://en.wikipedia.org/wiki/Bascule_(horse)I've heard that some of his babies are a little kooky and hard to start but once they are under saddle and going then I've heard good things about them so I dunno. He looks cute even though he's super on his forehand and he has a nice flat jump which is what they look for in hunters so if you get the lease then good luck!
Well all I really need is my butt to sit on that wicked piece of horse, so really everything else can be put on the table as sacrifice!! And I'm not even a hunter, I'm a jumper!If I was a hunter rider I'd up you my right eye for a Popeye K son! I say go for it, it would be a great opportunuty for you
