I have been watching a local youtuber that strictly euro nymphs. He has about a 9 foot leader out his rod tip and straight mono all the way to his reel; the fly line never comes off the real. This technique could easily be accomplished on a spinning outfit.

To me, fly fishing is utilizing a fly line to create energy in a rod to present a fly or flies.

What is your definition?

Not hating on anyone or bashing, just curious.....
