Thanks mobohuntr. I haven't looked at Easton Arrows. I have used Beman, but I thought for a 29" draw @ 70# I should be using Beman 400s(something like 8.4 gr per inch). Wouldn't the 340's be a littleweak spined?

{Edit after looking at the Beman Web Site}

You're right!!340's are the correct size.After adding in 15 gr (5gr each) for vanes and 5 for the insert I would be just over 420 with the Black Max.
