Talk to me about Lowline cattle

My wife talked me into buying 3 Lowline cattle ( a bred cow and 2 heifers) last fall.  my son showed one of the heifers at the county fair.  She was the only heifer in her class and got a blue and won the breed class by default.  I like the heifer because my son, wife and daughter like her, but my qyestion is, "How will they compete out side of breed shows?"

Thank you in advance for any opinions. <beer>
