If you're in the bubble, wait for a bit because we will have a CG next week.
You can also catch a carrier to colonia for a headstart if you want.
I'd recommend stopping in eagle nebula because it's been built up a ton and it's very picturesque. Also to see how far along the colonia bridge is.
Do all your engineering in the bubble, and have materials for jumponium just in case.
A Caspian is the way to go, it makes travel very quick. Spansh will give you the most efficient route.
For recommendations, I watch galnet digest, buur pit, commander exorcist, xpeigh, midnite black, and cmdr Precambrian mollusc for updates on colonisation
