Does Angler Pressure Make Trout Eat Smaller Flies?

This is a link ...   Angling Pressure Mean Smaller Flies?   


Normally I don't do external links but I found this "article" in Field & Streams blog " Fly Talk "  very interesting and it makes me think that the argument has some merit. I think I'll give it try in  late  spring or early fall of 012'


Of course, it may just be the 4 glasses of Pinot Noir that has opened my mind to such a possibility...
