I use a Biscuit and yes, my vanes are waveybut honestly it doesn't affect my arrow flight at all, like you would think it would.When I first experienced this I went to the pro shop and asked about it and my buddy said if you watch an arrow during flight in slow motion you will see the vanes become wavey naturally and doesn't affect the flight at all.
I found this intresting but he was right. My arrows fly consistantly with each shot. They do look funky though.
