Suggested blokade run :Take the JH from Rishiri to Lyonnais ( B4 ),
then in Lyonnais jump the hole to Lorraine ( G1 ) .
Lorraine is an open crossing through gallic space, but in some distance of anything but patrols : Jump hole to Champagne is C6.
Be careful not to get caught by gallic forces and don´t fuzz with the local brigands, only Council is really friendly.
Be careful with bribes, you don´t want to ruin your rep.

Suggested trade back : same path, other goods.
Promethum is selling very well in Liberty for research at Hamilton in Ontario.
But be very careful not to be seen with the stuff in Kusari : Kusari and Gallia are still allies, and we are doing blokade running here, ok ?

I suggest taking the Rishiri <> Tottori JH ( C/D 6 ) , sneaking through Tottori to the Tau 44 JH ( B 2/3 ) and slipping through the Taus to Bretonia.
( E6 to Tau 23, beware of the Sulawesi Citadel, then F/G 5 to Tau 29 and either the Baffin Highway home or slip past Tau 23 (F/G 5) <> Tau 29 (B 4/5) <> Tau 31 (G 6) to Newcastle )
(alternative route : Rishiri ( F 5 ) <> Hokkaido ( C 6 ) <> Kyushu ( B4 ) <> Tau 29 )
(( EDIT : due to inRP error and ooC agreement we have been asked not to pass by Rousillon JH / location is secret )
Other sellpoints are Munic : Planet Nuernberg ( all the way through Kusari, be careful or take the Omega highway ) and Canterbury Station in New London.
Pick up some Heat sinks, HPA or bretonian tradeables on the way back ?
Remember ; even if you are not trading contraband , the stuff is restricted to Gallia as far as Gallia is concerned. So dont flaunt it in front of any Kusari pilots, ok ?

Another nice and short way back takes you to hop to Burgundy first.
JH in Champagne is at D/E 2 , bringing you to 8k from Macon base, selling Samarium for a dream price of 288c / unit.
You can jump directly back to Lorraine from there and leave again.
Sell right next door to home at Duluth in Minnesota for 3991 c / u. AND you can use the lanes all the way from Rishiri.
Just don´t let yourself be cuestiioned too much by KP.
