Hey Guys,
I tried a bunch of your suggestions and a few of my own ideas and nothing seemed to work. I knew it wasn't my form becuase I can usually tell when I screwed up and it happened with every arrow I shot, no matter what length, weight, spine etc. I even added extra string silencers in hopes that would help. Then as a last resort I tried shooting a glove instead of my tab. BINGO! Problem solved! Now, if they fly to the right it is because I screwed up the shot. Thanks for all the help and suggestions. I guess shooting a glove changes my anchor point just enough to make the difference.
Mike
