I am not yet certain, but the problem may be fixed. I took the bow back and the pro realigned everything. Once the WB was straightened and secured, the nocking point was only slightly high. He decided to shoot 25 arrows through the bow and recheck everything. No movement detected. Besides the fact they forgot to tighten the WB firmly, the pro believes we were experiencing a fair amount of stretch in the string. I have now run appx 175 arrows through the bow, so I hope my problems are behind me. I shot another 18 tonight and it seems fine. After a few more days of shooting, i will regain my confidence with the bow and should be packing em tight.
