We have pretty limited experience, but have used him. Have a cow by him that is OK. She has some big bone under her and looks like fairly a typical black maine cow. She has been a decent cow, but is currently on the short list to cull due to this is the second year in a row having calves with crooked right hocks out of Angus bulls. We bred him to a commercial Angus cow and had a decent bull calf that made a county fair steer. Same with a cross bred limmy-angus cow. Basically he will throw a decent hip and the cattle have been sound. Definitely puts some hair on them. His front end will follow the cow's type, so use a good fronted cow. He won't really take anything away, but bred to good cows, the calves are nice. Birthweight seems to follow the cow as well (ranged from 65 lbs. to 90 lbs.). I think we had a nicer calf from the one cow bred to Slam Dunk that we did same cow to I-80 and having used I-80 now, I think I would use Slam Dunk before I-80 unless I needed to clean up the front end, which is where I-80 has the advantage. Slam Dunk seems to throw better rib capacity than I-80 for us anyway and I liked his calves better than the couple of Tysons that we had. Never could get a heifer calf. If I wanted to make a bunch of half blood heifers, I would breed him to some decent Angus or Sim cross cows.
