I am looking into getting new arrows for the season and am wondering what fletching to put on them. They will be used primarily for hunting and have always just used the 4" vanes. What is the major benefit of puting on blazers or a quick spin fletching. I know that quick spin is suppose to make arrow fly staighter, but if you bow is tuned properly and your arrow is straight, are they necessary or do they benefit. How about benefits from the blazers?
