Yeah, and besides......
Yeah, I agree with mjyp, and besides, I have even SHARED some of my flies with gentlemen who asked me what I was using on the stream when they couldn't connect. "WE AIN'T ALL SECRETIVE, YOU KNOW"!
Others have helped me when I started out - spread the wealth! I particularly remember one young guide, on his day off, who took me under his wing, gave me half a dozen good flies to use, pointed out the best lies in that section of river, and we spent some pleasant time fishing together BSing on the way back to the cars. He didn't want anything, either, except a light for his cigarette, as he ran out of matches.
