The only thing that has deterred me personally if the German opener where they skip the SZ111 attack and use 3 Subs in 106. One plane goes to Italy and the rest land in a manner that they can be used to hit the surviving British ships wherever they go in the Atlantic. If the UK wishes to try and make sure their ships go down fighting G2 then the SZ97 attack will be skipped in order to keep air assets available. The Bomber (might) be used with the 109 DD to try and hit the German Subs off Canada, which is a big impact already on the odds at SZ97.
