Do you think if his offspring start proving themselves more people will be open to this type of cross even if it is not sired by Cardi but is by another well bred cob stallion that throws that type of movement? I am sure some of the breeders in the welsh world would be able to point towards the bloodlines that could consistently throw big movement when put to the right mare, and the stallion might have been campaigned in something else (driving etc.).
It is true that there are few people breeding purebred welsh cobs. The count for 2012 represents one of mine. I put on the ground one purebred and one 3/4 bred that year. This year I have produced one purebred. It is also true that many of us who do breed them have our own stallion. One of the best things about Welsh Cobs are their versatility; so, yes I think those of us who are well versed in the breed could point to the bloodlines which consistently produce big movement whether they are demonstrating it in harness, in the dressage court or somewhere else. The one thing to always keep in mind that if dressage is the goal, the welsh cob who is produced for it must like to canter and find cantering easy. Putting a good trot on a welsh cob is one thing, making sure it produces an equal in quality canter can be quite another but there are the bloodlines that do it consistently.
