We practice QDM and I feel it's about both the herd and antler size. Our first goal was to get a better buck to doe ratio so we could see a more definitive rut and achieve a balanced herd. Our current goal is to allow the bucks to reach maturity unless an "inferior" younger buck presents itself. It's not an easy thing to pull the trigger on a spindly piebald and use your only buck tag for the year. If we can get rid of the piebalds, our herd seems to have good genes. However, we would all like the opportunity to take a Pope and Young buck from time to time.
