Helium from Pennsylvania to Okinawa planet, and plutonium back to Harrisburg
station. Optionally helium3 back to planet Pittsburg (watch out for Kusari authority)
If you feel more adventurous, helium to New Berlin The Ring
and black market ammo back to Allentown base Pennsylvania.
Uhm ... helium in Pennsylvania is not even slow to mine ... You mine it really fast there. Just watch the video, it will show you how to mine it the right way
May I ask what ship, ID, IFF and guns are you using to mine Helium-3?
You should also consider joining an official mining/hauling faction such as the IMG| where people often mine for each other and go on large convoys together to sell the ore and make a good profit. That is a great way to learn some new trade routes, get rich and have fun with a group of friends.
Run Reinforced Alloys from Planet New London to Oceana Shipping Platform in Cortez. For return trip, grab Synth Gel on Planet Curacao and take back to New London. Otherwise, we try to put some Platinum Ore on the station, and you can return that to Waterloo Station in NL for better $$$.
