I often use the "project" tool path. I create a 2D pocket path, then project it onto the surface. It keeps your end mill climb cutting, extends the tool life and delivers wonderful results.
One hint though, when cutting an inside pocket with vertical walls leave a small amount in the 2D path, say .001" so the 3D path doesn't "climb" the vertical walls of the pocket. I usually finish the vertical walls with a 2D or 3D finish path first, then project onto the face.
Project also works well to "clean up" surfaces that other tool paths won't finish properly.
