WOW some great responses.
SNAX, great looking bait, any feedback on how it produces?
The more calories gained for less calories expended would be how a fish would think (if they do indeed think), as well as nearly all other animals (us included). I have read, over the years, that this is how they work.
I know when I have been trout fishing in the UK that when they are hitting the pin fry that you wait for a splash of an attack then cast a fly into the distrubance. The trout will then come and mop up the fry damaged, stunned in the initial attack. And with the your fly in there too, more often than not it gets taken.
I would have thought that this would be the same for all other fish.
