Total concur with the arrow weight, I shoot 420g Axis End Fussed Easton and can tell the benefit of the added weight. The Mac Daddy was a little lose with the Carbon's 3/8" STS and had to use a little electrical tape with the 3/8 shaft. Works great. The stock sting dampener only last a short time on my Pantera and prefers no string dampeners as the best set up is the Limb Saver and NAP apache stabilizer with the Mac Daddy string stop.
What I plan to put on the Bengal. My Cheetah has an S-Coil the Alien has an X-coil (didn't change it out when I bought the bow)
