That is the only negative I have w/ the WB. BUT, it can be remedied. Use a hair dryer to heat the vanes up and USUALLY they will flatten back out as you run your fingers over them.

Blazers are the best I've found w/ the WB, they don't wrinkle at all. If you need to refletch your arrows, you will need the fletching jig of your choice and the glue of your choice. You will need something to scrape the old glue off. There are some commercially available fletching strippers out there that work very well. I just use the serrated edge of a pocket knife, you just have to be careful not to cut the carbon.
