Well, I have to ask: Let's say that the 'tests' and 'experiences' described in some of the above posts clearly identify that, beyond any doubt, the conclusions are: 1)It IS the Material used in the construction of the fly that was the difference in catching and not catching trout; and, 2)The ability(ies) of the fisherman had little to do with the catching success.
Which brings me to these questions: Why not use some Lure Scent or rub some insect lubricant to the fly or even impale a real insect to a hook (like a catepillar or cricket) and continue to call it 'fly fishing'?
