Okay, here is my setup, Darton Mavrick, 70# with about a 28 7/8 draw, 27 1/4 arrow, release, whisker bis. rest. and Left handed, and a 100 grain thunderhead, may switch to a mussy. I was shooting xx75 eastons 2314, maybe should of shot a 2315, and just switch to a carbon Beman 300. The new dealer got me to switch to carbon and he set me up with a ICS 300 camo hunter. Now that i did some research later, I see the charts say I should be shooting a 400. The arrow is a ICS Camo Hunter 300 that was issued to me. Should a switch to a 400 or stay with the 300. I know i should shoot both, but should I even buy the 400 to see or will the 300 do. What is everyone else shoot with 70#. Any feedback would be great. Mark

So nobody can help me?????

I think you're overspined. According their arrow selector you should be shooting at least the 340's but you're borderline 400's. I'm in the same boat ... I'm shooting the 340's but I'm borderline 300's. LOL
