I noticed that it seemed to wreck the leading edge of my vanes, but after switching to the B2 the problem isn't so prevalent and there are no more annoying black streaks on my vanes. When it comes to ruining fletching I think the biggest culprit is my bow. I upgraded to a Bowtech Patriot a couple weeks ago and now I sink arrows fletching deep in my Target Bag and Bales the local club; in three weeks I have effectively stripped two dozen arrows.

Anyhow the pro's outweigh the con's, I wouldn't trade the biscuit for anything. The reason I got it in the first place was for when I've been sitting in the tree for 5 hours and its 10 degrees out; I don't have to worry about shaking the arrow off my rest while drawing.
