Greg, this is just my personal observation. Easton's website and advertising does hightly tout the FMJ, but it is of my opinion that its because its a new offering and they really push the fact that with the aluminum cladding it will pull easier from 3D/broadhead targets. Other than that I cannot see any reason why or how it would be considered better than the ACC or A/C Superslim, maybe as good? Having said that I am biased toward the A/C Superslims(see signature).
