RE: NAP QUICK SPIN VANES
 

They fly great, for hunting I used them a bit to test. Indoor league as soon as they get hit by another arrow they get pretty banged up.

I have used both the 2.5" and 4" and personally do not think they
are worth the cost.I could not get the 2.5" to stabalize an arrow
with ANY kind of broadhead. The 4" gets the job done but with a
lot of noise in flight and extra weight.

The bow "pro" at my bowshop said that the wing on the edge of these actually makes the vanes "lay down". He said that there's so much force on them that they actually bend over, decreasing the surface area, which is why you got them in the first place. He said they may make your arrow spin a little faster, but with decreased surface area in the back, it becomes less stable than an arrow at normal spin. (I wish I could draw a picture, it really does make sense!) So you're gaining spin, but losing stability, which isn't an even trade-off. Also, they are somewhat fragile compared to other fletchings. I'm shooting the Blazer Vanes, and they're really durable and I don't have any problems with accuracy.

p.s... Blazer Vanes in RED, WHITE, AND BLUE!!!!!!!!!!!!!!!!!!!!!!!(to remind me to give thanks to the men and women who make this country the best in the world, and giving us freedoms; like the freedom to hunt and enjoy life. just thought i'd throw this in here!)

I could not see any difference with the 2.5 vanes. Shooting broadheads or field tips at any distance.
