Even the growing in popularity, "friesian warmbloods", I think are pretty awful. I have yet to see one that I like, they seem to inherit the bad genes :/ Long backs that don't swing, hocks that don't actually come under the horse, upright neck, big heads and far too much hair.
Then there's the standardbred crosses. I can count the number of standardbreds that I would have liked to ride, on one hand... and not towards the fifth finger either.... WHY would you cross them with other breeds such as quarters horses, appies etc. WHY??? I've seen a stb x friesian, NOT a functional horse in any stretch of the imagination, but because it had 'friesian' in its lines and was black... people fawn over the god awful thing.
