You don't need to line them up. It has no effect on your accuracy. As long as they spin without wobbling you are good.
no kiddin.. yea they spin great i had just heard that even if u spin test them u should have them inline, what your saying does make sense though
As Rybo said; they need to be balanced and in-line with the shaft. Aligning them with the fletchings does nothing for you.
Well of course you do, Vito. Everyone knows that. If you don't your arrows will be mathematically imbalanced which will result in erratic flight, poor penetration and sorry blood trails.
