Good point about the field points. If you shoot into a bag target for practice, you definately don't want your field point to have a bigger diameter than the shaft. Otherwise the the backside of the point catches on the bag when you pull out the arrows.

My biggest question with the Axis arrow is the durability of the shaft at the business end of the arrow. There is nothing in the area between the insert and the shaft end to protect the shaft end from cracking or splintering. My concern is that a slightly angled hit could crack the end of the shaft, especially if your field point/broadhead loosens up a bit in flight. I would think that the potential is also there for stress fracturing of the very end of the shaft just from the repeated pounding of the back of the field tip directly onto the edge of the shaft. Time will certainly answer these questions. Personally, I hope these arrows prove to be durable. They will be the ultimate hunting shaft.

By the way JeffB, have you had the chance to check the spine consistancy? Do you think these shafts will be resilient to spine degregation?
