Have you got rid of those gazzilion squad types for all sides? There was like 15 for French infantry only. If you have German OOB, I can filter it through Tessin.

Battle of Britain was something I was thinking of too - short, lot´s of data available, small map to create... the problem is that airfield bombing is way to effective and the German would cripple the RAF in a couple of turns.
IIRC there is specific bit in AltUse to set is as Airfield Attack. Maybe reducing number of actual devices will lower number of destroyed planes? I do not think bomb accuracy have much effect on this.
