RE: Vanes what ones ?
Whisker buscuits really like Blazers. They are rigid enough to handle the abuse of the friction w/ the bristles.
For that matter, Blazers are an awesome choice regardless of the rest. They stabilize broadheads VERY well, and don't weigh as much as 4" vanes.
If you want the "cool" factor, go feathers. Nothing compares to feathers, in the cosmetic department anyway. Only 1 negative, they really don't like to get wet.
