Blazers are the way to go. Ive tried them all and found no reason not to use blazers. That is for hunting purposes. They are the most durable vane ive ever used. Ive got a few arrows that have been through several animals and never need to be revaned.

Feathers are great too, i use them on all my trad bows. Just make sure you either use turkey feathers or spray your chicken feathers with silicon spray so moisture doesnt cause them to fold up. Heck, you need them for trad bows because a shelf or knuckle will eat up a vane in no time.
