The 3rd canal; Skagerrak--a rules change proposal...

[TG Moses VI]

I sure it'll work out for the Germans being able to launch surprise inf/arm assualts into Finland/Norway with the support of the Luftwaffe.  This forces UK/USA to be cautious when landing troops there.  However, I think that this should be more of a "Germany only" type rule.  As SUD pointed out, with the Allies also having the ability to Canal Cross, this forces Germany to keep troops stationed in the Fatherland, not pretty when you're also trying to hold EE at the same time.
