With todays center shot tuning aids like the laser tuner and the level systems made, is paper tuning obsolete? Kinda, A laser center tuner is hard to argue with. It's obvious this will give you perfect center fire and the levels will get the arrow coming out pefect and you can get your nock high as you see fit. If it doesn't paper tune after that, perhaps spine is wrong and/or your torquing the bow.
