I'm a promoter of Rendition, he actually was born not that far from my house-- regardless... when I saw him in Denver (last time I saw him), he excelled all other bulls in the yards in terms of a cattleman's type of a bull, that could work for all aspects of the industry- seriously.
I know Woody kept telling us, and the people around us.. that he'll be best suited for mating to Angus cows. I don't know if that's to take advantage of their homo black (since Rend is hetero, and throws some crazy colors), if it's so Rendition can inject the blaze face (almost too much white on Sim's), or if it's to help cap into the ever growing Sim/ Angus craze.
Regardless of that, I think if being mated to Sim cows, the ideal cow for him is a homo black, solid black cow... that is unless your a clubby type Sim person and want all kinds of crazy colors.
Offspring pictures, do a search both on here and google.. There are tons that will show up.. He becomes a topic of discussion about once a month on here.
