I have seen a couple of threads mention broadhead and vain alignment, and I have read on eastons site about certain inserts to allow for proper alignment, especially since I am about to invest in a dozen new arrows, but is it really that important? What is the proper alignment? Are the vains and blades supposed to be perfectly straight? If they are off a bit, how much will that affect flight, accuracy, speed? If they are not aligned, how can this be acheived once your arrows are already made?
