I like the fish head idea, as it is something harder for me to mess up! Very worthwhile data possible in a few years. I do know that many of my large HSB (8 lbs and up) have survived about 5.5 years so far. The 2020 stockers range up to about 5 lbs, so there's a clear differentiation.

Think we can safely conclude that many HSB at my place survive longer than 3 or 4 years. Beyond that, who knows?
