I don't think it's the line either. Granted, the Scientific Anglers Sharkskin lines have the rougher texture, and when a bonefish peels away with my fly at 28 miles per hour (bonefish swim roughly three times the maximum speed of trout), I do feel it. But I've found the texture of the Sharkskin actually alerts me to the line abrasion in my hands, so I let go of it. I actually get cut less with Sharkskin. I worry more about the smooth line that you don't feel biting into your fingers... often times, I'll cut myself stripping and making casts, and and won't know it until I look down at the blood dripping off my fingers.
