Brad, Angus never really got too big in the whole scope of things. Major showers did get too big in the 80's, but many ordinary breeders weren't there yet.
The trend smaller catches the followers who have never caught up to the bigger cattle and they breed down fast.
Lines like Traveller 23-4 will knock frame size off cows so fast it makes your head spin. Putting it back on while maintaining thickness is tougher.
NR our 20-30 traits are 8-10 epd ranges, white, feet, fertility, disposition, pedigree, length of body, frame size, legs structure, shoulder smoothness, breeder integrity, loose skin, longevity..... probably more...many are covere in eye appeal, but that is a huge generalization. Importance is debateabl, depending on where or how we are using said genetics. Some things are not negotiable, some are flexible with in reason. Bottom line is the bottom line.
