Good memory! (That or I’ve said it way too many times)
Yes, I absolutely believe that a heavy US buy in the Atlantic turn 1 and 2, combined with heavy Pacific spending the rest of the way, is part of a winning formula for the Allies.
By the end of US2 the Atlantic usually looks like this if I’m playing the US:
8 loaded transports, loaded CV, DD, C (this can vary: maybe one less loaded transport and an extra CV or a couple more DD, etc. Depends what Germany looks like). From there I spend the rest in the pacific each turn, save for a couple of loaded transports, or men in a complex, etc.
