I think the fresh, bright pinks are pretty good; but have seen some 'zombie pinks' still struggling around beyond their expiration date. These things are decomposed but alive somehow--literally fins falling off/flesh chunks falling off/jaw dragging in the gravel. I was fishing for silvers once and a zombie brushed against my line, the goo was so bad I nearly barfed. Had to spool off some line and get a new leader. Seriously that bad. And some guy was completely ignoring the mint bright silvers in the river and loading up his trashbag with pinks. He grabbed one and it looked like it slipped out of his hand, but it actually slipped out of its own skin. Just said, "Ah, they smoke up a fine dip."
