I have been considering getting one of the Sharkskin lines. Every review I have read talks about the sound the line makes as it is going through the guides. For some it does not bother them, but for others the sound seems to be enough to keep them from using the line. I ran across the following video and you can clearly hear the sound this line makes. I thought it might be of interest to someone interested in the line, but is concerned about the sound the line makes. You can decide for yourself. For me, I'm on the fence about it.
