[Fog of War] - Large Scenarios

[Hugmenot]

Has anyone experimented with Fog of War house rules for large scenarios involving 150 units or more?

I've played a number of large scenarios from Kursk: South Flank and Workers and Peasants and the current rules are a prime consideration when the attacker has objectives as victory conditions. This is even more true if the attacker has both control some hexes and exit a number of steps objectives.
