After checking out the links above, I would say ask yourself what your dog's genes would do to benefit the breed?
For example, my youngest worker is going to be used at stud assuming he completes his health tests successfully, mainly for agility dogs, but also for some going to work in their field. He is small, lightly framed, so perfect build for an agility dog, very high drive and is showing huge potential in his training, he also trains as a gundog and is also doing very well, as well having a fantastic pedigree behind him. So you need to look at what your dog will pass on that is desirable for a show type cocker.
