Keep in mind they need to have some sort of offset or helical to them. If you fletch them straight they will not work much better than any other vane. If you want straight fletchings feathers work better because they have more drag and a natural curve to them even when fletched straight.

However with a small amount of offset the blazers should work well. I tried them this year and the spin my arrows about as good as 4 inch feathers or normal vanes. The are VERY stiff so they catch more air than a softer vane would.

I don't know if I like them yet, but I won't deny that they work.
