If you dont bend at the waistyou will not have the same anchor point and believeme, I know from experience. Last year I missed a 9 pointer at 3 yds and 22 ft up. That is why this year I installed a kisser button. When the kisser is in the corner of my mouth the only way I could make a severe downward shot is to bend at the waist. The kisser forces the bend if you know what I mean.
