I shot with another traditional shooter at a 3D shoot a couple of years ago. He was telling me how he had only found a couple of types of arrows that he could shoot because he needed so much length. The variety of shaft he had found had an outsert to add the extra inch to full length shafts. I can remember watching him shoot, coming to Full Draw ? with 5 to 6 inches of arrow projecting past the end of his riser.
Maybe there was a method to the madness after all.
I think the old easton arrow charts recommended the extra inch and that is what I have gone with.
I draw 29.5" with my recurves and 29ish with a longbow, my arrows are 30.5" to back of point.
