yeah it is a tough call, because of my profession I think of it not from experience but through theory and the way I see it is that the veins are going to be more stiff on the blazers and therefore when the arrow is rotating, the veins are more sturdy and not flapping around due to the wind drag. I could be pulling this outta my ... but it's a theory. Also another theory is the blazers have less surface area for wind to grab onto when shooting in crosswinds.
