Just like every method there is always a window of illegalities... agree with many of these spey fishers abusing the limitations. Indies have been abused for quite a few years now... so I hear you on that. Just like any other method falls victim of bad intent.
Should a spin fisher not bottom bounce a fly because its against an unwritten rule???
Or how about a fly fisher dead drifting a sac??? How dare he???
For the maritime spey fisher, spey fishing was invented in Scotland on the spey river, so maybe if its done anywhere else it should be called something else???
Now, I'd love to fish large water for salt run salmonoids. And I would love to fish the traditional styles... but don't think these sink tips and what not that many folks use on these traditional rivers can't fall within the guidelines of bad intent. Seen fish get flossed with sink tips and no weight...or a tube fly swung with no weight... and if i were fishing large water somewhere and happened to find a run that I felt like high sticking a nymph through with my two handed...you'd bet your azz I'd give it a shot if the traditionals weren't working. And if any two handed maritime snob shook His head at me I'd be thinking about telling him to shove the butt of his 16' fly swatter right up his azz and suck on it afterwards if he had a problem with my methods...
Just get out and fish...bottom line...
