Yeah...i'd definitely be looking at the Angus bulls real hard. such as I like Simmental & % Simmental cattle, I don't think that's what I'd do on a Limousin female. A couple of those bulls help do some of the things you mentioned, but I don't think it's the best cross for her. The reason we breed Simmental is because of how well they crossed on our commercial crossbred cows back in the early days, and you'll get more heterosis out of a British x continental mating than by going with another continental bred sire. The Hereford thing could actually be interesting, too, depending on the bull. I don't know much about them right now, but they seem to be gaining some steam in this part of the world, and I think they're better cattle than they have been in the past. The champion horned female at our state junior livestock expo this year was as good as any female of any breed there, but I have no idea where she came from or how she was bred.
Out of the Simmental bulls you listed, Dream On would prob be my pick, and i think there's a good chance the calf might not be good enough to justify spending that much on semen. Sheriff Taylor is interesting to me in pictures, but his numbers are weak & I haven't seen a single calf by him. I think Sure Bet could be the worst decision you could make on that kinda cow & wouldn't recommend him at all. Goldmine can make some nice females, but I don't recommend him in this scenario either.
