Hi Mike
This is turning into a good discussion I wish more people would come in here
I agree
Relating to spiders and their effectiveness is a typeset example were correct fly design works to maximum effect in fast broken water.
The same fly used in different circumstances is far less effective; reasons are behaviour of the fly is paramount to success.
Again history tells us why the old timers never fished still pools and flat water with spider patterns. Unless it was windy that is.
If we take for discussion the standard tied Greenwell glory as a prime example.
Waxed yellow thread body.
To light for a Dark Olive and to dark for a Pale Watery.
But yet it works in these very circumstances.
Logic tells me trout do not see as we see.
I think it is correct to say presentation is directly related behaviour.
If presentation is incorrect it will not allow the fly to fish correctly
Prime examples of the theory would be.
The correct fly used by a poor angler would not catch many fish. But on the other hand the wrong fly used by a good angler would still succeed.
Other things also make up the difference here for example accuracy in dry fly fishing etc .
Its a very intresting topic,There are many point of view on this,each person will have there own points of view.
Correct or incorrect and thats good.
What did Stewart say we only need 3 flies
