The WB is notorious for wrinkling vanes. They even say so on their website. Although, they do claim that it will have no effect on accuracy. A solution that I used and likes was to refletch all of my arrows with Arizina Archery Enterprises, Speed Flyte Vanes. These vanes are durable and don't wrinkle when shot through the WB. I own a chrono. and gained 9 fps when I swithced to these vanes. I had Duravanes previously. These were on the arrows that I bought at the pro shop. The shop charged $1.50 to refletch the arrows with me supplying the vanes. If you can't find the vanes they are available through Cabela's. Make sure you don't buy the AAE Plastifletch as they will wrinkle a little also. The Speed Flyte's won't.
