Kind of depends, I would think, on what you're wanting to produce... show cattle with lots of hair, etc... productive commercial-oriented cattle... superior carcass traits.... solid color, red/black, baldies...the list goes on and on.
We've stacked Shear Force in our breeding program through the use of several sons & grandsons - really liked my Singletary (sire of Cowboy Cut) calves - daughters have been great, steers were scale-mashing rascals. But, we're strictly commercial, with no registrations... have no idea if any we've produced would be of any interest to anyone in the show ring.
