I want to get it off if it's not needed or I want to use it if it's going to give me better performance.
the vang and the traveler system control two different aspects of the sail trim. The traveler controls the horizontal angle of the boom relative to the centerline of the boat while the vang controls the vertical angle of the boom relative to the mast.
When running, you'll probably need to let your boom go almost 90 degrees to the centerline which will give you little control over the vertical angle no matter how you set the blocks on the traveler. To keep the free end of the boom down you'll need the vang whether in light air or heavy. In light air the vang will also lessen the bouncing of your boom which spills what wind you have and slows your boat.
I'd keep the vang
