The best one is the one that you decide suits your needs best.
Both excellent shafts, each has their strong point. If you want an all-around general purpose shaft, the a/c/c would be my pick. If you want a hunting shaft only, well, I'd probably still go with the a/c/c, but the FMJ is still an excellent choice.:wink: (I don't really have shafts that are for hunting use only)
