I prefer vanes. I like the fact that I don't have to worry about them in bad weather. I still think they tend to hold up better than feathers. I don't usually shoot groups once I"m dialed in so I don't have to worry about them getting buggered up.

One thing I"m noticing from shooting 2" vanes is they hold up better for some reason. My buddy is shooting the Blazers and that is the way to go IMO.
