    getting a chill and ill be shooting 70lbs and a 27in draw and im gonna go with ss inserts in my vaps…they are the 300 spine(they are the arrows i have from my 80lb MR7)and that is overspined according to victory’s spine chart with the aluminum insert in them…but the ss would add about 50 grns and i ran it through the OT2 shaft selector and it said that that would be the correct spine to go with here are the numbers…

    optimal spine-.3105

    F.O.C.-1791%

    velocity-254.3

    KE-66.26

    just wondering if this is correct, or if anyone has experience with the ss inserts. :thumbup
