Best thing to do is walk through them and look at them, there will be a few that catch your eye over and over, these are the ones to break down from bottom to top first, grade them on a scale:Attitude 1-5, structure 1-5, depth, width, topline 1-5, ease of movement 1-5, over all look, and wow factor 1-5 (Clean fronted, smooth shouldered, big furry ears, cocky look) Tally up their score. After all that look at what bull their out of, some times you top 2 or 3 will end up out of the same bull, some times your top 5 will be out of 5 different bulls.
but in the end dad buys her the one she wants because it is cute or is pretty colored,

I can't tell you how many times I've seen a better calf pasted up that cost the same or less because they want a red one, a baldy or something out of a particular bull.
We always sorted through the calves and sorted them before we looked at breeding ( in steers) I think it helped keep us honest in our appraisal of the animal.
