One thing i noticed when travelling -800ly > -1100ly below the Horizontal, across one end of the Galaxy to the other end (for the last 4 months), is that Neutron stars are everywhere with distances averaging from each other at 50ly-60ly, unless you hit dense fields. So get a ship average jump distance of 80ly, you then can reach 80% of all neutron stars in single jumps from one end of the galaxy to the other at -900ly > -1100ly below the horizontal. I have yet to find any area on the map, except near the edges of the map, where i can't use just Neutron stars.
I have yet to explore in depth at +900ly > +1100ly above the horizontal, but it is safe to say it is nothing like what i found in the depths of the galaxy map.
I tend to use them now as a subway to move rapidly from one area to another, across the map.
