I use the scimatar vqariant with falchion wings. The wings add some green spots to the design without going overboard.
I like the tulwar too but imho all those lights are a wee bit too much. Add an aegis set to it and youve got a ship straight from vegas.
I use the romulan 2 hull and windows type 2. no pattern. looks more romulan than reman. i like the hull textures that come with the ships but imho its way to different from the other ships.
