I just switched from feathers three weeks ago. Shooting through a biscuit - they really surprised me how well they really work. When they arrived in the mail I was like "What?" these are way too small - wondering if I ordered the wrong size. They've been shooting well out to 40 yds for me no complaints.

I was using 4 inch vanes. The local pro shop that I used to refletch my arrows closed so Idrove out to tha big place in Lancaster and bought every I need to do it myself including Blazers. I got two different colors, one for practice arrows and one my hunting arrows. They work great.
They work very well...I have been using them for a couple of years and they are hard to beat.

Blazer vanes do work very well I used them last year and the year before. However, this year I switched to the new rayzr broadhead feather and have found them to work even better when using broadheads.
