Variety is the key most of the time. I got to witness this first hand years ago on a coastal river for fall salmon. 4 boats anchored in a row, everybody throwing eggs and no catching to be had, fish all over the place. It was then a drift boat came down with some clients, anchored above us and put the smackdown on 3 chinook with the quickness using eggs as well. There's always that one potion that will get inhaled. That was the last time I left the house with 1 type of cured eggs.
