I am planning on asking my parents for one of these for Christmas this year. I know that alot of people recommend a bitz but its just out of my price range right now. I shoot Blazer's and I hear alot of poeple saying that its better the shoot them offset. I was looking at the options for the Carbon E-Z fletch and it only gives a Straight and a Right helical, no offset. Which one should i get to shoot blazers?
