I'm happy to spend my time looking over starships and willing to go into fetishistic detail. just so long as everyone else is.
Whether GT:Far Trader is compatible with earlier versions of Traveller appears to be a bone of contention on the T20 forum, with a lot:
"It's a big ship universe that supposes large volumes of planned trade which take no account of communication lages"
"It's always been that way"
"No it hasn't"
"Yes it has"
So I don't know how compatible it will be with Maerdwyn's vision
Anyway, the GT:FT model involves working out each worlds potential for trade (WTN) - which is based on population, tech level and starport classification. Bilateral trade between any given two words is the sum of their WTN , adjusted by distance, and their relative classification.
This means I am in the middle of working out 400 trade relationships; however a pattern is emerging:
The Outworlds is a sparse area without a great deal of trade.
A lot of the worlds count as either Na or Ni.
Which means the few worlds that are either Agriculural or Industrial look like being key.
There is so far only a few routes that qualify as being a Feeder Route under GT (About 8 x 1000 ton frieghters + a dozen or so free traders), and only a few that would count as minor (Half a dozen lines, half a dozen tramps, all well <1000 tons)
The feeders are:
Maakar - Qaran.
Er - Qaran and Sham
The minor are:
Qaran with Er, Phonwit, Karell, 945-755 and 807-946
Gergigi with Ishga
Navarino with Ishga and Phonwit
Ishga with Er, Phonwit, Karell, 945-755 and 807-946
Er with Phonwit, Karell & 807-946
Iceball with Qaran and Sham
Revelation with Qaran
That's as far as I have got.
The two worlds with the highest potential (WTN) are Qaran and Phonwit
However Qaran is an industrial world in a sector which has few, wherehas Phonwit is both Non Agricultural and poor.
Maakar is fairly important, but a bit isolated and both Na and Ni
The agricultural worlds, in declining order are:
Karell and Er (Amber Zone), then Revelation
The only two industrial words are Qaran and 807-946 - at opposite ends of the sector.
If we were going to target a single planet, the best bet would seem to be Lizir - which has no starport & hence even less external trade than you might expect from a world with low population and low tech
