Telos, do your hardcore's milk??? When I think of building a herd milking ability rises to the top. I have a few hardcore's and honestly they about starve their calves. Don't get me wrong, good look and powerful would be traits I would describe them with, just not maternal.
As far as Benz, I'm not sure if you can answer the question of maternal power quite yet. I would say that benz's mother and both flush sisters have as pretty of an udder that I have seen on a Maine cow, so I would think that should be an indicator of some traits that will pass on. I definetly agree with McCartan the Benz calves have a killer look and come small enough that a herdsman can actually sleep at night. Our Benz calves have had great bone and plenty power. I know Bushy Park Farms has had some great ones this year out of him. I thought 3 of the best cow calf pairs last weekend were due to the Benz calves on side.
We have never bred to Joe, so I could not comment on him.
