Well at $20 for a dozen arrows worth of vanes and pay someone $2 - $3 to fletch them it can get very expensive. If you don't fleth oyr own arrows you are gonna spend $45+ just to have fletchings on some arrows.

And feathers still work better than any vane made. That's what I reccomend.

A $10 broadhead lasts a heck of a lot longer than vanes do.
