For 3D I prefer to use the smaller diameter arrow due to how the wind affects the larger diameter arrow. If I were strictly shooting indoors, I go with Carbon Express Line Jammers.
Easton X7 Eclipse 2613s for indoor 20 yards. I am going on my 3rd year with the same dozen and every one still spins true......except for the one I accidentally closed my bow case on.
I'm want to go to a few 3ds this year so do you this i should keep my Easton lights speeds for that? I don't really feal like changing my rest for hunting then change it for 3d. Think i might stay with my mid size shafts..
