We have used him on our commercial Red Angus herd. He sure does a good job of putting more growth into those cattle. Since he is a non-spotter, non-diluter, the calves don't stand out like a Hereford bull would. He does mark his offspring though, they tend to be a lighter shade of red. One of the most remarkable things about that bull is the quality of semen. I don't know if it is consistent or if the stud collection just did a great job of collecting him, but we used 30 units and got 24 calves. The RA bull that we used at the same time gave us a touch over 50%. This was in a group of timed AI cows.
Calving ease was fine, but we used him on older cows. Another thing I noticed about him was that his gestation length was notably shorter than the other bull we used at the same time. I guess that is how they bred calving ease into him.
We have a bunch of half-blood bulls out of him that we will use for the first time this year. If you would like I can see if I can get some pictures of them and post them. We had one bull out of him that was awful flighty but the rest of the group are quiet and gentle so I would tend to think that the one was an aberation.
All around, we are quite happy with the results of that bull, the only thing I think we are going to see from him that we don't like is his calves are probably going to have a higher mature weight than the rest of our cattle do.
