I've been shooting Axis arrows for the past 3.5 years, and I love them. I've had a few dozen over the years and I don't plan on switching anytime soon. They provide excellent penetration and great durability. I highly recommend them. As far as the epic, they are slightly larger in diameter for certain sizes and in the weaker spined arrows they are a little bit lighter. They also use the H-nock system instead of the x-nock. You can't go wrong with either arrow.
