I have been shooting the Axis since early spring and I really love them. The whole idea behind the shaft and its components is something totally new and innovative. I've had great penetration with these shafts which is the result of focusing the bow's energy into the ultra-small diameter, and with the combination of a small diameter and its internal parts, they are very accurate, and very tough. Its looks are somewhat desieving, b/c of its small diameter, you'd assume that it was a light-weighing shaft, but actually they are supirsingly dense. And because it's smaller diameter you will achieve speeds greater than those of a shaft equivalent in weight, with a larger diameter.
