What is the furthest "plus" or "minus" you've gone? Have you been beyond the
Thin Disk? Out to the edges of the galaxy, or is your range just for "travel"?
For me, I am trying to get as far into the edge of the
Stellar Halo as design and persistence in mapping can take me. An SRV may let me do things on the ground, but it also chops ~1.5 LY off of the ship's range.
While I know an FC could do it better, I also consider those to be a lack of comparative challenge. The recent CG to the top of the galaxy may have exceeded what my ship can do, but there was no skill involved. It was the Elite equivalent of the old D&D, "and the DM puts his fingers up your nose and says, Follow Me!"
