Artillery counter fire opinions & views wanted

[Gordons HQ]

I'm playing a game at the moment where we've said we will not to fire at these puffs of smoke as we believe it would be unrealistic to spot hidden artillery by this smoke.
So far everything is working out OK, although it could possibly be a problem if you wished to put area fire in a location for some other reason. I guess we will have to restrain ourselves if that is the case.
Our rule is the enemy artillery has to be spotted by someone with a radio before CBF can be used.
I think it all depends on how realistic you want to try to make your game and trust your opponent.
