Niner, Im using the long ones for hunting.

I have spent this week shooting them with one of my bows and have come to the conclusion they are not quite what I want. They seem louder than other fleatching and they slow down the arrows at long distances. I noticed a drop in my arrows from 35 yards out. I am not impressed with there durability either. They seemed to booger up real easy.

Ont the up side, they did spin the arrows well and caused them to have a better flight. I just personally dont thinkNap isfinished developing them yet. Great idea, just needs some bugs worked out.
