I have been fortunate to shoot both, and I would say to go with the FMJs. Reason being is you do not have to worry about the collar splintering out on a hard impact. I have gone through a couple of the Axis from hitting hard targets such as trees, where the collar will splinter out. Regardless, you cant really go wrong with either. I will say that the FMJs are slightly harder to fletch using Fletch Tite. Just be patient when you fletch them and they will settle nicely.
