Let me start by saying I am a huge fan of the Guideline shooting line and have used it exclusively on my 7wt spey for the last 3 years. I've also used the new Rio Powerflex on my z-axis 5126 with positive results last season and will only use floating shooting lines. Well the Guideline on my 7wt finally began to wear out and it was time to replace it. On a whim, and because I got a good deal, I thought I would try the Sharkskin line out. I had test cast a full trout line in the past, thought even though it was very "slick" I didn't care for the noise, but for a shooting line who cares? (it wasn't very noticable for the record).
So my official opinion on the running line is that it really shoots much better than any other floating line I have used. I liked the gray tip where it connects to the head for low light conditions and it was quite impervious to tangles during casting. My only complaint, as you might guess, is that it is indeed abrasive when stripping in on wet hands. I have had other lines do it too after long days in the rain, but not within an hour. A strip of electrical tape solved the problem (probably will use a bandaid in the future). All in all I felt the qualities of the line were worth the inconvenience of protecting my finger and I would recommend this line with the fingers caution.
There you go. My
