Most accurate arrow rest alignment in one simple trick. 

Update: Since using this technique, I've also improved my form. By making sure the forward sight is perfectly inline with the "at-draw" plane, "at rest" plane and arrow rest, you can see how much influence your putting on your string or bow at full draw. How many times have you adjusted everything on you bow to be fairly accurate but your front sight alignment is to the left or to the right of the arrow - the string and rest alignment? Put your arrow in the rest and look down the arrow and align it with the string. Where is you front sight? Is it left or right of this plane? If so, you ARE influencing your string with your form and thus will never be as accurate as you can. After a year with this set up and practice and everything in perfect plane... my fletchless paper tuning is perfect and accuracy is best I've ever had. Everything is in plane and I've relearned how to have "zero" string influence. But this is only done if you perfectly align all the planes and work to not have to adjust your front sight left or right. Thanks for watching everyone, I'll make a video on this soon. It's exciting and will help many.
