On board artillery spacing

[Weasel]

I was wondering what you guys think about on board artillery spacing? I know that myself, and all my opponents, always put at least 5 hexes between tubes, which is inaccurate. In real life a tube may be 50 yards from it's neighbor, but not much more then that or else command and control breaks down.

Do you think that some form of restriction should be created to go along with the FOO rule, for example 4 tubes in an 4 X 4 area max or something like that? This would also force the buyer to purchase transport for his tubes too, which would also be more realistic, after all the boys didn't push that 155mm there.

I know Shortreengage and myself tried a restriction a long time ago, I think it was max 2 hexes between tubes.

I am just noticing that with the FOO rule on board CB is not really an option now.
