Vanes are better for hunting. I like the lower profile 4" and I believe duravanes are the lightest. Even their tougher vane for the wb is only 9 grns. a piece, a blazer is 6+, higher profile and stiffer, the opposite of a feather and a detriment (deflection issue). Vanes a quieter and in my recent test more durable. Both smacking each other the feather needs refletched. By the by, 2 arrows, one with a vane and one with a feather hit that close together.
All bohning vanes are heavy than the duravane counter part.
Feathers are beautiful and forgiving to deflection, lighter as mentioned, considerably and as mentioned you can cut your own. Goose feathers were popular in Europe's days past and still are there. Turkey feathers are a relativly recent item, (we have them here in the states

). Right wing and left wing mean just that, the wing they came from. I've heard that if you shoot right, get right, left, get left.
Enjoy them both. Have somefeathered ones fordays that pleasant. Have vanes for everything else.
