Bear Claw, as long as your bow is in perfect tune youcan use a strait fletch with zero offset and your arrow with broadhead will fly strait. With that said this past year I did use the quickspins, with a one degree offset. When I use different vanes like the blazer, duravanes and others I use a strait fletch with a five degree offset. I like the quickspins because it does help shrink my groups, but the down side is they are a bit more noisey. Now about the wind, well no fletching will help your arrow overcome/beat the wind. If the wind is blowing it can and will blow your arrow off course. How much willdepend on how far the distance is to the targetand howhard the wind is blowing. Plus arrow weight and speed factor in as well. Like a bullet a heavy arrow will not be affected as much as a lighter arrow in the wind. With elk hunting I would have to be hunting in hurricane winds before I was worried about my arrow getting blown around. The reason why is because my shotshave beenand will continue to be close and my target/vital zoneis big. On the other hand with muleys and antelope the shots can be longer andthe vital zones small. The wind can play havoc wtih accuracy, so shooting in strong winds with the quick spins or helical fletchingyou could have a tigher group but youmightnot have a clue on where that group will hit until after the first shot is taken. I will not shoot over 40-45yards at any animal, and if the wind is bad I will choose to get closer.
