The swap seems like a good idea. I don't disagree with flytire's or your points, I just think the cutters are fun to work with. I don't tie flies to save money, I tie for my own enjoyment and because I feel a need to only use flies I tie. I often tie a great many flies just to learn a pattern and in time, after the volume that I tie, I think these cutters will not seem so expensive. They were pricey, but I gotta say, they are well made. Shortly after I opened the package, I had cut enough pieces for a several dozen flies in many colors.
I also don't think that they would do a better job catching fish than any other foam hopper, I just thought they were cool.
I also had to report on the superb customer service that I got from RRC. Seriously nice people- they really went out of the way to help me with a mistake I had made.
