I had two Goldmine calves born about 3 weeks ago and they are looking pretty decent. Nichols Manifest has also thrown some pretty good calves bred to cows like this.
For a simmi take a look at STF Royal Affair. He's a Lock N Load son out their Onyx cow whose offspring have collected a pile of banners and sell for $$. I believe they have sexed heifer semen available on him.
Simmy I would go Grandmaster or Upgrade to get out of the Dream On influence and get some great females. Also would consider Sheriff Taylor for something older school.
I second SVF Allegiance. They are just hitting the ground but so far I'm impressed. Very stout with good bone and body at a young age. His dam is a grand-daughter of Dream On I believe, but it hasn't stopped me.
