I originally thought this was more gimick than technological advancement. Then I started reading reviews and watching Youtube reviews, and thought there might be something to it. I then thought the price was too high.
I received a new 3wt rod as a gift and went to my local Gander Mountain who had the 3wt SS line marked down from $60 to $15, so thought "What the heck?" I even bought some traditional 3wt thinking I might not like it. Well, I've fished Wisonsin, Illinois, Colorado, New Mexico and Utah so far with that 3wt rod and the Shark Skin hasn't come off yet. The buzzing sound is not annoying after a short bit, and I have actually have another cue to use to tell how I'm casting (especially on roll casts).
As far as the fire pole analogy, I'd agree with you, but guides are hard and skin is soft, as far as your fingers are concerned, it's a cut, not a burn (and yes, that part stinks). All in all, I love the Shark Skin.
