I had been using a WB rest and changed it out to a dropaway. With the WB my FP's and BH's had the same POI. With the drop away my BH's started hitting 2" low as compared to my field points. I felt certain that my bow was tuned properly, needed no adjustments but here is a problem. I talked to several people and they suggested to sight in for BH's and forget it. I couldn't take that advice, I wanted to know what was up. I decided to raise the poundage up on my bow to 70#, it was set at 65#. I had no good reason for this other than wanting to see how fast my bow truly was and if I noticed any differences setting my bow at max. The first thing I noticed is that the BH's and FP's now shot at the same POI. Now my issues are fixed but I don't really understand why unless I have a spine issue with the arrows I am shooting. Could I get some answers to this from some of you guys?
