If you want to stay with percentage Simmi, W/C BF Innocent Man is really popular right now. Looks like he will make heifers or bulls. Banshee at Pinnacle Sires to keep them half blood but you might get a little more white than you want. Style (Angus) is super hot and I have seen some really good ones out of purebred simmi's.
If you want to go clubby. I really liked Who Made Who on Simmi females or finding a new bull to try in Denver is always fun this time of year.
