Steve, thank you for your quick reply. Are there any other modfications for the 2nd edition (only for Lion, I found on CSW the new rules for Eagle)? Where was new 19.8 published?
As regards your point about the interception phase, I like to think that I am picking off the enemy bombers that are at the back of the formation which the enemy fighters ignore (or just don't see) because they want to fly on towards the target with the bulk of the bombers.
Make sense to me. As an RAF beginner I'm not sure if it better to attack with CE (add its combat value) or without (more gruppen, worse column).
