Just an opinion. keep in mind that archery does not have to be scientific. Different shooters hold the bow a different way and torque has a big play in arrow flight along with the way you release the arrow. Thats why I'm a firm believer that a properly tuned bow thru paper is a must. the sooner the arrow is stabilized immediately off the bow in flight the less work you vanes or fletching has to work to get that arrow stabil. If that makes any sense.
