THE FLY --IS OR NOT.
That is a good question and l do not think there is a absolute answer, it is more the individuals train of thought, at least that is mine.
Of course there is a major difference say betwen a Adams and a hook with just a copper wire winding on the shank, they will both catch fish, thats is a fact.
I know that this very issue has caused a geat deal of controversy in the past and has lead to certain named (FLIES) being banned from use for one reason or the other.
In the real sence the art of fly fishing is to use a fly that is in some way a representation of a food source a fish is likely to see.
A fishing fly, lure call it what you will is a means that you use to decieve a fish, nothing more. You cannot duplicate the intricate structure of a natural organism for a great many reasons, which l am not going to deal with here, but you an get close enough to decieve the fish.
