WOW.... and the advice is "just move your sights" ?!? Are you serious ?!? LOL!
NO, when you add 30 grains to the nock end of your arrow you obviously need to check the tune and then RE-TUNE your rig! Then you begin the sight in process!!! No different than shooting different b-heads..... you do NOT just simply move your sights until you assure that your arrows are flying perfectly straight!
