I am using Beman ICS Hunter 400 arrows. I use 100 grain points and the total arrow weight is 403 grains. I haven't been able to chronograph it yet because I put a .22-250 bullet through my chronograph a few weeks ago, and I am waiting for my new one to arrive. I shoot the same arrows from my Q2, and it is set up basically the same as my Cybertec. They chronographed at 274 fps. out of my Q2.
