If you tune a bare shaft to fly the way you want it to,and then start moving your side plate in or out,then you are totally changing the way that bare shaft will fly.The problem with most folks is,we tend to shoot arrows that are to stiff,we get stuck in the bare shaft tuning rut and only watch the straightness of the shaft in flight or how its sticking into the target,that is a problem causer,believe me i have fought it for years,ESPECIALLY(spelling??) on bows that are not cut past center.If you are shooting the perfect arrow ,it will wrap around the bow just right to shoot to where you naturally look,like I said,ive been fighting this problem for years,(just always had to have that perfect bare shaft).Now when i tune,i like my bareshaft to hit 5-6" to the low right (because of bow cant)of the small dot I'm shooting at,at 20 yds,then my fletch arrows are dead on.
