RE: fletcthing for aluminium arrows
You can use any type of fletching on aluminums you want. By the way I have blazers on 2213's and they work great, why wouldn't they work with an aluminum? Your going to have to explain that one to me.
The type of fletch you use is going to be more dependent on your shooting style and rest choice. If you are shooting a rest with no contact issues then vanes are fine, as long as you don't use a lot of helical. If you have contact problems with the rest or shelf then feathers would be needed because of the forgiveness. Like shooting a long bow off the shelf would not work very well with vanes, and some rests for finger shooting are hard to use with vanes.
