With constant badboy the only way to trade in wine is to own the provinces and the CoTs in question. Prawnstar what are your desired slider positions? I'm going to hazard a guess at As Centralised as possible (always best), Aristocracy (Cav and leader shock), Innovative (WE max +2 might be useful)??, If Innovative allows Serfdom without being too behind. Mercantilistic, (no point trying to trade abroad), slight def, heavy land since Europe will support tons of ships anyway and 1-2 Quality to ensure victories through Europe.
Of course given Prawnstar's history this is 90% bollox and he's going to win with full decntralised and switch to tribal to make it interesting.
