OK I didn't express my opinion/experience with the WB. I will tell you that at one time I did use one. It was tuned to my bow and I shot pretty good with it and harvested several deer using one. But from day 1 when I switched to a NAP Apache drop away my groups improved I would estimate 50%. Shooting 2"-3" groups was the norm with the WB. Once the Apache was tuned groups at 20 yards were now well under 2" and busting nocks and ruining vanes was now the norm until I got smart and started shooting at different dots on the target for each arrow.
