I just caught a typo in the new issue of Peterson'g Bowhunting that gave me a chuckle. On page 122 on the arrows and broadheads page of new products, they talk about the new Blazer Vanes by Bohning. Here is what it says:
Bohning challenges archers to "Just shoot it". See for yourself why Bohning's new two inch Blazer vanes give hunters the steering cababilities of a four inch. The Blazer weighs in at only 5 pounds ( yes that is what it says) and the lighter back end of the arrow will give you an increase in Front Of Center (FOC) for better arrow performance.
Man I don't know about you but I can't see an extra 15 pounds on the back of my arrow helping with my FOC a whole lot. Of couse if you are shooting the Bohning 4 inch vanes you are talking 30 pounds on the back of your arrow so I guess 15 pounds would seem to help it out a bit.

Man am I glad that I shoot AAE 5 inchers
