Like I said, release weights are the flavour of the month. The more research I have done, the more I am unconvinced. But...I'm no marine biologist so if the powers that be say its the way to go, then who am I to argue. I catch to keep, so when I have what I need, then I stop. You will have the unexpected catch which I try to release quickly as best as possible. Do the bread & butter fish survive, especially undersized, maybe. Who knows....
