After talking to josh I think that this bull would work on a variety of cows. I think for me the attraction was most due to his dam. I think the best mating would be on cows that have a little sim in them. I don't think he will add or subtract frame. I think he may add some milk but not take any away. I think he will add middle and clean up fronts and add some muscle. I think he will put some decent steers on the ground and his heifers will be able to be used as breeding stock. And I think his bw's look really good. So my answer is I think he would work on about anything. I would tend to use him on cows that are about where you want them. I personally am going to use him on two Hairy daughters from two separate cow families, a whiskey daughter, a Nichols legacy g151 daughter, and a commercial angus out of OCC Legend. I use I think a lot because it is my opinion, but those calf pics especially the one out of that bodacious cow helped. I recommend calling josh. Like I said he is super nice and helpful. Hope this helps.
