To maybe start an argument but all in good spirit: Is "bead" fishing really flyfishing just because it is on a flyrod?

I guess my real question is what defines flyfishing? Anything fished off of a flyrod ala Situk; all mono and yarn balls with splitshot? No lead unless tied on a fly? Only way to truly get fly into zone can be from proper mends and actual flyline/head with no extra weight added to leader or fly?

A plastic bead pegged above the hook (dont get me wrong here as I know the effectiveness as I stare at my dads 15+ lb upper Kenai bow from Sept 09) with split shot seems like drift fishing. Drift fishing is cool and way more effective on drift gear. If I throw a pink plastic worm on my flyrod and catch a steelhead how did I catch it? Does it even matter?

Cheers
