I just did a Pearl variant that worked out ratehr nicely…
Pearl with air only, plus my DST (lost my SUB in UK1).
I took out the Pearl fleet, lost the DST, and landed my FIGs from the attack on an AC I have moved to Wake.
That left my AC out of range of much of the air power normally available for a Pearl counter (Western FIG and Eastern BOM were out of range). That would ahve left the US attacking a loaded AC with 1 BB, 1 TRN, 1 FIG. (almost 50% US would be wiped out in that attack).
And it kept a BB off Japan to cover my TRNs, and I still have an AC and BB off Kwang.
In short, I got Pearl and almost the entire British navy (they have 1 TRN in the Indian Ocean, and 1 SUB in the Pacific) for a cost of only 1 SUB and 1 DST.
