My personal experience with him is very limited.
I bought a cow, from where I work, that had been AI'd to him. The resulting heifer is, so far, one of the better looking heifers I have raised. If she has inherited her mother's ability to raise a good calf, then she will stay here. She is due to calve in 2007.
Not much info, I realize, but something is better than nothing ;-) .
