I am too lazy/smart to bother reading this entire thread. But do want to note that with hard work, perseverance and innate ability one can achieve proficiency that exceeds their peers in any method and that the level of difficulty in achieving extraordinary proficiency at any given method can be extreme. Yet climbing that pinnacle does not appeal to everyone, nor should it. (I think in some cases the quest for perfection takes all the enjoyment from the activity.) Many just want to have a good time on the water.

I will be the first to admit the float and jig fishing is relatively easy. Hell, that's why I like it. I like catching fish. But try keeping up with Nick Amato when you are both fishing floats and I'm pretty sure he will school ya. I see even less skill required to huck a fly out there and let it swing across the river.
Bill Herzog wrote what many consider to be the quintessential book on drift fishing but thinks mastering spoon fishing is more difficult. In his opinion swinging a fly is the least demanding way to fish. Note least demanding and most productive are not the same thing by a dan site.

I enjoy it all including fly fishing. It seems to me that whoever has the most fun wins. If you can have more fun than I do and avoid thinking you are somehow superior because of the method you choose you are a real winner.
