I have very simular specs, but I shoot at 70 pounds. And I recently purchased the new Easton Axis Arrows. In my opinion they are the perfect blend of speed and kinetic energy. You woud probably use the size 300 shafts, which would put you right around 400 grains. If you are using a drop away rest, these arrows would be a good choice, if not, still a good choice, but you would have to watch how much helical is used in order to get good arrow clearance.

Good luck,

Jason
