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
