So far Ive hand straightened all my cedars and Doug firs. Are they perfectly straight like a carbon or aluminum? No, but then again they fly just as good and hit where im looking anyway. Anytime I hear where someone is concerned about little irregularities in wood, I remind them of how much more imperfect cane arrows tend to be, yet they fly as good or better then any other material. The main problems you get into with less then perfect shafts, is not in shooting or accuracy, but in painting and cresting....which I dont mess with any way.
