I've read before, that an arrow going 250 fps is making one complete turn every 3 feet. The broadhead blades and the fletches are not going to cut through the same piece of air, so it doesn't matter if they are aligned. I've had good luck with a paper tuned bow and Slick Trick standards with Blazers or 3'' feathers. The Blades were not aligned with the fletch, cause there were 4 blades and 3 fletches. With the same bow and arrows the Muzzy 4 blade did not fly so good. Some broadheads fly better than others. The more or bigger blades you have, the more the broadhead will try to steer the arrow. Think of broadhead blades as fletching on the front of the arrow that competes with the fletching on the rear. A compact head offers less surface area and reduces the chance of wind plane.
