I was thinking of trying these vanes and was wondering what everyone thought of them? I currently shoot easton diamond vanes and have heard alot of good things about the duravanes so I thought I might try them. The 4 inch vanes are advertised to weight 8 grains per vanes, and the easton vanes are 8.2 grains per vane. This should help my FOC a little. I will be using them on carbon shafts cut to 30 inches, 3, 4 inch vanes, and 100 grain muzzy's. Tell me what ya think, and good hunting this season. Bhunter32.
