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