For anyone that is going to be @ the Iowa Beef Expo this weekend, look up Gracie Russell's steer out of Wilson on a Heat Wave cow. He'll work well on stout/hairy THC. Not a lot of semen left on Wilson. Available through owners, Jeff Maas, Tracy Goretska, Top Sires, and Champion Gentics, Texas.
depends on what you are trying to accomplish but some bulls that work on th carriers are: alias, yellow jacket, or other charolais bulls for south...for north, if you want steers use a pha carrier such as irish whiskey etc or you could consider power bulls that are clean like one and only or bulletproof the new bull at denver I heard was very nice...
another bull i have heard good things about that is a pha carrier is BK Navajo...i think this could be a very undervalued bull....especially with irish whiskey now at $200/straw....
