I would think that if the Momma's Boy's calves were world beaters we'd have heard more about them, but it could be that old fact that there just really are no run away bulls in the Simi sires. Some 1/2 bloods that we hear more about are SOS, Maximus, Mossimo, Sandeen's Salute,(Joe/Kris Knowles bull), and one that I am watching a little harder again would be RSVP. Seems like there are a fair number of RSVP's showing up as Momma's.
