I guess one could argue that they aren't truly fly casting, but undeniably they are fishing with flies using a form of fly rods...that spells fly fishing to me. Heck, Dame Julianna wouldn't recognize what is today's purist fly fishing. I say do it however it pleases you, but I feel it is a mistake to put a severe limit on the definition of the sport for everyone else based on a personal bias.
A right emblem it may be, of the uncertain things of this world; that when men have sold them selves for them, they vanish into smoke. ~ William Bradford
I finally realized that Life is a metaphor for Fly Fishing.
