If your looking for a carbon hunting shaft, I would take a look at the new Easton Axis shafts. I just got my dozen and are in the process of putting them together as we speak. So far, I very impressed with the straightness of them and I just spun six broadheads on a dozen shafts and all but two were perfect[

]. Very cool setup.
Time will tell how they hold up, but I think JeffB could answer that part of the equation better then me right now. I'll start shooting the snot out of them this weekend though.
