They are finiky when it comes to fletching them. I've gotten to where I figured out how to get them to fly decent but not where I want them to be. I just ordered the Bohning Helix jig just for the Blazers...gonna try that dude out since it's suppose to fletch them the way the factory recommends them. All my friends are shooting Blazers now so I need something to fletch them really good for them.
I've not tried the Fusion vanes as of yet but I have tried the AAE MaxHunters. They are basically the same shape/design. Out of my bow with the same arrow, they are nearly 10 FPS slower than the Blazers. Don't ask me why but they sure were. I think they catch more wind or something. Probably fly better in the long run of things though.
