I disagree. Just because it is popular in MT or WY doesn't mean it should be used in SD or further east or vice versa. Also popular doesn't always mean good. I have seen alot of the popular sires out there and wouldn't even dream about using them. Alot of the popularity comes from a great picture, super EPDs or even if the ranch that produced it is more popular. It doesn't show udders, or feet, or even production records. If you are chasing something, that is what you will always be doing, chasing. Try leading. All you need to do is lead your commercial customers with great genetics, and with what they need. Not what some college or semen company tells you what should be used. If you do this you should be successfull and have happy, and repeat customers. My customers never ask for a certain bloodline, they just ask are they good again this year.
