hello. I have removed the torpedo belt and was surprised at the effect it had. I probably could have added another double turret, but I am not a fan of 6x2 arrangements. better to have a 4x3. I am okay with a 5x2 arrangement though I played around with the idea of a 2x3 + 2x2 arrangement. didn't like the idea of two unique turret types.
