We've got some good Lead On and 7229 cows. Those are the only two we've used, but they have worked well for us. The LO cows could get a little too wet, but if paired up with lower milk production type cows, he hit a home run. 7229 has worked well for us in our search for a good cow maker. We have not had any feet issues, but we make the heifers jump through several hoops to make it to the herd...maybe some were culled there? He can moderate frame in 1 generation, which we like. Only had 1 calf that he did not bring frame down on...it was a steer, but son of a gun was he good! Thick as the day is long and puppy dog gentle. We put him in the freezer and he had a big, WELL marbled ribeyes and the meat was great. Of course, some of that was the finishing ration.
