Their vanes weren't destroyed from the wisker biscuit. More likely pass throughs dilapidated targets. Countless people and I have thousands of arrows through a biscuit with absolutely no damage at all. Not even one vane ever. All different types of vanes. Using blazers right now.
Anyway, I hear about it very often. Guys don't even shoot their bow for a year and go hunting. One guy at my work just had to get a new bow string because it broke after using it for 26 years.
