We had a limo that was no fun, unless you got off your horse and walked with a stick. That he understood, and walked on home like an old milk cow. He wasn't the least mean, but rather simply didn't grasp how the horse/bull relationship was supposed to work, seeing as he had never seen a horse before we got him, which is my major complaint with most purebred breeders anymore. The worst in this country have been Hays Converters, Limo and some red Angus, according to the guys on the Waldron. These darn bulls are getting so huge that it's a bit frightening when they as tall as the horse you're riding! Last hereford bull we had when we were looking after another person's cattle (we didn't pick him), was literally bigger than my 15 hand gelding. He must have been a pretty ugly BW too, because we had some HUGE calves, and those huge dead calves don't pay well.
As far as monopolies on prolapse, that was the reason for staying with those couple of breeders, as we went for years with zero prolapse, since any prolapse and anyone remotely related to her went down the road until it wasn't a problem anymore, but after looking for a bit of outside blood, ran into it again. No breed is perfect, and I still like a black baldy best, but as I said, hubby is liking them all black, and he is the one who calves them.
