I think building FTR for ITaly is going to give the most help to the London attack, Perhaps he will be needed to clear blockers on I2 or even as a defensive unit after the capture on I3.
I think Germ should send both the CA and BB to block and build a dd or perhaps 2. It might be necessary then to put the fleet with CV in sz113 to stay safe from Allied air. Germany’s objective is to block the relief of England, UK’s objective is to sink those TRNS!
Also, based on the results, provided UK can safeguard sz 106, wouldn’t it be better to build 1 trn in Canada, then he can bring 9ipcs of units over the next round. Who cares if he dies at that point, he has increased your def of Britain. Basically spending 7ipcs to bring in an inf/Arm.
