Don't concern yourself with the sires. Look at the mamas of those heifers first. Evaluate the cows, then compare with the calves. For Club Calf production, look for square angles, straight lines, excessive bone, muscle and hair, along with deep bodies in both the cow and calf. Buy only a heifer which has the phenotype you desire in your future calves. Regardless of the sires you use, expect to have some calving problems, and little milk production.
