Spine consistency is KEY, and is the most CRUCIAL part of the problem here..not the straightness. If spine and weights are very consistent, then a moderate straightness (.008-.010 TIR or so) is not such big deal for most archery applications

AMEN to that and the fact that alot of archers are underspined due to the fact that they want to shoot 280 fps or faster , does not help them especialy this time of year when they start screwing on broadheads .
