So I guess there goes the whole "Aerodynamics" thingamajigger? I am thinking the lower profile the fletching and the straighter it is, the more accurate and faster the arrow will be. On a long shot, at the speeds of todays bows, I can not see where a helical will amount to a hill of beans difference. jmho Now if you have some of the gosh-awful huge bladed broadheads on an arrow with blazers, I guess it could pose a problem, being that the huge blades of the broadhead would overtake the steering of the fletching. Does that make sense?
