The transit method of exoplanet detection relies upon the disk of the system to be edge on to our point of view. It seems the wobble method would be able to detect wobble from any angle. Or does the wobble method depend on the Red/Blue Shift, only being able to detect if a star is moving closer/farther? Can the wobble method only detect to-and-fro, or can it detect left-and-right if we were viewing a system from above/below? As far as we can detect, do most systems share the plane of the Milky Way galaxy or is it a pretty random assortment of orientations? For that matter, is the plane of our system level with the plane of the galaxy or are we at an angle? EDIT: Sorry, for light I suppose it would be the Red Shift or Hubble Shift. I had posted "Doppler". My bad.
