Looking for some clarification on arrow spine. I have a Mathews DXT 70/28 bow that I am trying to tune. I have been trying to elminate the nock left condition. I am shooting GoldTip 5575 per GTs guidline. I would prefer to pick the proper spined arrow cause from what I have read seems spine is more important that rest. I have tried 85gr and 100gr tips and the difference seems mininal in terms of correcting the problem. I am hesitant to but new arrows (7595s) right now. Anyone have this problem before.
