ALright this is kinda ignorant being I have been doing this for awhile but heck I have to ask.

Out of a properly tuned bow, do ya really need to do it? I guess here is my take on it.

The arrow is spinning creating an unstable airstream by the time the feathers get there anyways. Now maybe in superfast stuff say 300 plus but heck even then, the arrow is gonna really be spinning. Now I am no scientist but in theory it sounds good.....how about in reality. I havent done it for more then a few years, I know of others who are the same and I know others yet who swear by it.....so whats the deal.
