Someone mentioned the axis. I personally shoot the axis with my razortec and my friend shoots the 400's out of is vipertec, not sure what they chrono but it is quick and he's had pass through's on all his deer so far. 27.5" draw, 62lbs 100gr. muzzy 3-blade.
We were testing a new target a couple of weeks ago and in a brand new target I was getting 8" more penetration from an 9.5 gpi Axis shaft vs an 11gpi carbon fury and the same from a 8.2 gpt goldtip XT. Those axis shafts were almost going as deep as my acc 3-60s. I was very impressed with the axis shafts. There has been some bad press on these around here but sometimes rumours tend to take on a life of thier own real quick. I remember reading one person saying they warped just resting in a corner. A friend of mine is testing them this year and so far they are proving to be excellent. If they continue to give that same performance I will likely switch to them next year myself.
