Fish - I have never said that Popeye K had to be a dressage horse in order to be approved for the Hunter division, and I also don’t think that you will find that in the KWPN-NA rules. Just because some posters think he should doesn’t make it necessarily so…
Tom - I don’t believe that you would be happy with Foalbook mares? Remember, it’s almost an unwritten requirement for the dam of a stallion prospect to have some kind of predicate and also come from a mareline that’s not lacking in them. So no, you don’t HAVE to present your fillies for studbook, but I would consider that a rather shortsighted view.
As far as good hunters being a “by-product” of standard breeding goes… well, yes that’s the way it’s been handled by the European breeders thus far. Here in the US however, breeding specifically for hunter qualities is considered a speciality. Just ask Trish Quirk who owns several well-known hunter stallions and is quite active in the showing of their offspring. I also submit to you that as a European you may not have quite the full understanding of what makes a good or great hunter. In addition to the performance classes there are also huge hunter breeding classes, with Devon, Upperville, etc. at the forefront. I would recommend you attend a few of those in order to get a better understanding of the discipline.
Also, just because a Hunter has been put into the Hunter Book of the KWPN-NA doesn’t mean that all breeding for hunters will only occur within that division. Breeders, with the advice of judges, will be able to designate which of their foals go in what book.
Specialization has been implemented, and as much as you may or may not agree with it, consider the Hunter Book simply an addition to the Jumper and Dressage books in this country.
Any other justifications will have to come from somebody more knowledgable when it comes to hunters. As it is, I may have already stepped on several toes with some of my statements regarding that subject.
