If your orange juice doesn't burn on the way down, then you need more vodka!
I am actually ordering a hexmap from Hotzmats.com for the game Canvas Eagles. I plan on eventually getting some Langton 1/1200 scale minis for Close Action and thought I could kill two birds here by odering a double sided mat with 3" hexes for Canvas Eagles and smaller hexes on the other side for Close Action.
I am thinking 1.5" hexes should work ok, but I am not sure. I basically just want the hexes to be big enough to account for the largest ship I would need for the game. I plan on making 'sleds' for the boats to fill the space in the hexes for smaller ships to make movement easier.
