I may be partial, but Leroy came to mind immediately when I read this thread. He will add guts to all his offspring. I have attached a picture of his mother, so you can see where he gets this from. Also, John Hagie ( Cyclone Trace) in Iowa, has recently added several embryos from Sparkle, as well as a daughter who topped the Fever sale in Olds, AB last week. Leroy will also add structural soundness if you need that. He is now 8 years old and moves like a cat. He walks from morning to night and still stays in excellent condition. He bred over 60 females this summer and came in from pasture in better shape than when he went out.
Semex International has the world rights in Leroy, and semen is handled by several other semen distributors in the US as well. He is the highest selling Shorthorn sire that Semex has sold, and he is marketed in close to 100 countries.
