Ha! the secretive business end!
A bait, any bait, without saying or explaining why it works, its advantages, its uniqueness, its capability/limitations (including what's in it), is simply another bait.
It becomes trendy and fashionable in the eyes of anglers if enough people use it on enough venues for enough time and word gets banded around. Inevitably some will catch big fish - and the undisclosed number of smaller fish too.
The quick route to market is to throw some money at it, offer some free to anglers, sponsor a few of the better ones and put a fancy label on it. What is truly fascinating to me (and I suspect many anglers) is the clever use of ingredients within a bait that can be proven to work without the need for clever marketing.
Above all else, the willingness to discuss and disclose what those ingredients are with customers.
The industry is far too secretive for my liking and I make no bones about it.
Respect to those who keep it real, open and honest.
