Pac Designs Messenger Bag: User Feedback Please

not wearing it right? not sure how wrong it can be worn. its on my shoulder, where its supposed to be. when you ride you pull it all in tight and high, then the plastic digs.

pac bags are designed to be worn on a particular shoulder, so maybe you're jsut wearing it on the wrong side? that would have the effect of the strap being effectively upside down, so maybe if you changed shoulders the plastic bit would be at the bottom, out of the way, and wouldn't dig into your shoulder?
