So you're looking for calving ease? The bulls I use on my heifers are Grandmaster, Trademark, Built Right, In Dew Time, Shear Force and his son Added Value here soon. I have also used Olie, but he makes a more maternal look. She seems like she has enough depth to make a killer Grandmaster calf. A halfblood that I like is Mo Magic, and I have heard many good things about The Foreman. Both are most likely ones you would want to use after her first calf. I like Grandmaster for her and Built Right or IDT if you don't mind the close Dream On.
