Don't quit, it can be fixed. It is either form, or a tuning issue;
From Kelly's site:
D. If, back end of arrow kicks left horizontally, (Opposite is true for left handed shooter.) shortly after leaving bow, but then later corrects itself and flies straight there could be one of two problems. First off, re-check your brace height to see if it has decreased. If so, increase it until this characteristic disappears. Second, there could be a fletch contact problem with shelf and/or rest material. Observation of shelf material usually will indicate a contact/wear point if this is the problem. Remove, shorten or separate the shelf material until this characteristic disappears.
I wish I could help more with Carbon's, but I don't know much about them. But you may want to check out Kelly's charts, which I have found to be about the best for traditional and cross reference the spine (arrow deflections) from an aluminum to a carbon:
