My question wasn't so much whether it was legal or not in fly fishing only waters. The regs clearly spell out that it wouldn't be.

It was more about being a "purist" or not. I think some people, especially that breed of fly fisherman who believe that fly fishing is the be all end all, get too wrapped up in the whole fly fishing thing and forget that fishing is about having fun and experimenting with different ways to catch fish.

Judging from the responses its nice to see that the majority aren't "fly fishing elitists"
