I'd totally approve higher risk commodities with higher reward. Mainly contraband from house lawful station to other house lawful stations, preferably through the whole of Sirius (Rheinland to Gallia, for example. Bretonia to eastest Kusari, etc), buy price of 20M for a 5ker, 4000 a piece, and a sell price between 15000 and 20000 maybe? That'd give you a profit of 80M, but also a high risk of losing 20M.
