My understanding of feathers is that they are lighter, but cause slightly more wind resistance (which is why they stabilize arrows so well). Ibelieve that a 2" Blazer would have less wind resistance and would eventually overcome the lighter feather's speed advantage somewhere further down range. (Don't ask me how far.)
That is probably true to a point. However, if you rub your finger across a Blazer, you feel there is a little bit of texture to it; it is rougher than say a Duravane or Vane-Tec. It still does not grab as much wind as a feather would though. Also, Blazers are very stiff, which aids in their ability to steer broadheads.
