Yes, they are the same diameter as the axis. I dont know about the kinetics. The vap is a little skinnier but also you HAVE to use outserts which i dont want to do. Last the injection is similar to the VAP, however easton came up with a new insert so you cannot use standard bh's, and the selection of BHs for easton injection arrows is pretty limited right now. I hear they are going to come out with an outsert for the injection, but then again i dont want to use an outsert.so the fmj's are small diameter like the GT Kinetics and VAP arrows?
I was playing around with the FOC if I were to go with the Kinetic or Axis or fmj. I don't like how the 300 spine on the fmj weight so much per inch. My arrow would weigh a lot and if you take the VAP arrows with stainless steel outsert you have the issue of having a super heavy arrow weight again but better FOC. I am looking at giving the Kinetic Hunter's a try or the Axis arrows.shot easton axis for the last 3-4 years. Really like the shaft, very straight and super durable. The only thing is its very small diameter and if you wanted to experiment with a heavy offset....each edge of the blazer is almost off the shaft. I switched to Carbon express kv 350 this year. ( no particular reason just wanted to try another shaft) Just a bit bigger in diameter. Can't go wrong with either...both really good quality stuff. Once you pick the right spine play with your foc until you get the flight and flight in the wind you are looking for.
