If you shoot a whisker buiscuit or if you hunt with a fixed blade broadhead, then Blazers are a no brainer.

If you shoot 3D, you need 4" to stay in hunter class, if you want to shoot open (IBO of course) then it doesn't matter.

Feathers are great as well, but if they get wet, you are sunk.

I shoot blazers for hunting for the following reasons:

1) They are tough
2) They steer broadheads well
3) They shoot well off my bow
4) It reduces weight at the back of my arrow (always good)
5) They are simple to fletch
