Being somewhat less than young, I've been trying to outsmart fish for over 60 years. Much of my direct early fishing training stretches back two generations, to the late 1800s.
For me, going back at least 45 years, I came to the realization that fish somehow communicate over fairly long distances -- maybe up to a half mile. They also learn real fast. They somehow communicate to other fish that certain colors, textures, sounds, smells/tastes, and other "behaviors", etc., are something that should be avoided, no matter how tempting. About the only exception may be live bait.
From years of experience, it seems that any new lure/bait, except maybe for live bait, may work great for a while. The fish will become conditioned, and it will become ineffective.
It really comes down to constant change -- or natural/live bait.
