i think your talkin bout bareshafting.
WARNING: I PROBABLY DONT KNOW WHAT IM TALKING ABOUT!
but as far as i know, you dont fletch your shafts. just get them to the right length and what not, and add a point that weighs the same as your hunting points. shoot them like that. if it hits to the left, (for a right handed shooter, left handed will be vice versa) its to stiff. to the right, too weak.
i hope that answered your question.
