Easton X-7' s are an excellent choice if you want aluminum. At .001+/- straightness they are very straight and they come in many sizes to fine tune spine. They also are extremely consistant in arrow weight. If you are interested in carbons, I have just started using Carbon Express CX 3d Selects. So far I am very happy with them. They are listed as .001+/- straight also and they don' t bend. They are either straight or broke. Arrow weight consistancy is a small issue though. Even though they rate them highly from the manufacturer, this figure is taken before they are cut to size, of course. They may weigh more at one end and if you cut that off, that in turn affects the weight of the other end, the one you are using. But with the way these shafts are layer manufactured this inconsistancy is very small as compared to conventional rolled carbon shafts. Another shaft that I used last year and still may use this year are Easton ACC' s. They are a Carbon and aluminum shaft. They are very consistant in weight (even after you cut them) and the small diameter help to keep the wind from getting ahold of them with very long shots. However, you give up a little straightness because they are listed as .003+/- straight which still is pretty straight . I have also heard very good things about Carbon Impact shafts, but I have not yet had the pleasure of trying them. Good luck choosing!!
