All pretty nice bulls I would say. Ace of Diamonds is out of Wernacres Ace High, and Hi-View Zelda. Vogel's in Iowa have used him a bunch on Sonny and Double Vision cows, with great results. We used him on a Sonny cow this year. Sinister was raised by Sullivan's, and is out of AF SL Sin City I think. I don't think he's old enough to have babies yet, but I think he'll breed like his daddy..so I would use him on smaller framed, thick cows needing a little more frame and that "fancy" look.
