Interesting comment about KVD cherry picking the best baits. I read an article about ten years ago written by Rick Clunn regarding this subject. Rick said only two to four plastic cranks out of one hundred will run to his satisfaction. His words were “Very few baits will hunt”.
I still use 1oz circa 1973 Cordell Spot’s that are primo fish getters. They use a knocker instead of a rattle. Not much paint left on them, now that I think about it there isn’t any paint left on them.
