my question is why such a large diameter shaft? are you shooting 3d to cut lines?
or is the weight an issue the larger diameter will be stiffer and lighter, at that thou i would be looking at carbon shafts. i personly dont care for the larger dia. it makes a broad head look funny. and that thought what weight of point a hundred grain point will spine an arrow differnt then a 125....thoughts to ponder sorry for now real answers. auther p and the 2315 seems as good as shaft as any and there every where when you tend to run low...
thanks
