I first saw the Blood Vane after this year's ATA show. I got a chance to get some of the pre-production prototypes in January, and I have been testing them ever since. I think these will be a great option for bowhunters who aren't interested in investing in fletching equipment, or don't want to take the time to learn how to build their own arrows.
Installation is simple...slide the vane one, drop some glue in the holes, tilt that shaft to allow the glue to run along the channels, and wait for the glue to dry. Since the whole assembly is one piece, the vanes are super durable and won't come off like many other products.
If you are interested in reading a full review, or having a chance to win a pack of the Blood Vanes, check out my site... http://soleadventure.com/2012/05/gea...limit-archery/
