I have never had any experience with the Direct Hit calves. The red heifer that Logan showed the year before last from Majors was a Dr. Who, they had a great time we love her, she showed very well, never had any issues with attitude, we showed her as a Chi because the Maine division is so tough here in Kansas but she was also a purebred Maine so we were able to show at the Jr. show. We bred her to Hard Core and she had a calf that is a carbon copy of herself, good mother good udder not aggresive, the calf she had is an absolute puppy dog. We were impressed enough with her that we flushed one of our donors to Dr. Who, so I would say we would do Dr. Who again.
I guess in my book the bull really wouldn't be the deciding factor, the breeder should be able to tell you by this point what the personality of each of the calves are. With heifers we usually show 2, 1 a little more clubby and 1 more cowy that way we are covered for most judges, if I had to choose I would select the one that would make the best cow.
