I'm planning to make a trip to Arm's End - Hypau Aec IO-Z d13-0. Does anyone have a route?
The best route there is: 3 Geminorum -> Lyed YJ-I d9-0, visit the NSPs with the gyre trees and pods there (the trees look surprisingly good, watch out for the caustic cloud the pods can emit up close though) -> Angosk OM-W d1-0 -> some more NSPs in the Xibalba region -> Hypau Aec IO-Z d13-0.
Alternatively, with 60+ ly and plenty of jump mats, you can bypass the first journey down South and instead cross the inter-arm void SE of the permit-locked NGC 2286 sector, or for an even more challenging traversal, SE of the Skull and Crossbones nebula.
Of course, I assume you'd be looking for a route of exact systems go through the final stretch before the Outer Arm's end, but as far as I know, none have been posted yet. In my opinion, it's better that way, because the fun part of it is navigating your own way through that lengthy stretch of sparse systems, to finally reach that tip that might remain the most hard-to-reach place in the galaxy. If you just follow an exact set of systems to jump through, that requires little effort.
There's also the other one in the Tenebrae region, where I've yet to go, but looking at the map, that one would be easier to reach.
