Great question, you have the bad luck to ask a dedicated Cat Quiver user. From my experience adding a bow quiver to a left handed bow might cause a small change with your arrows hitting to the left. I would wait till you have your quiver on and remember to practise all your shots with the quiver full, minus one arrow. That way your bow will be balanced the same way for all your shots. Thats the best I can do for you, as I said earlier I use a Cat Quiver and don`t have your problem.
