My friend has 4 AP's and he wants to get a 15416CD.OO.1225CD.01

Here is what he has so far (all RO Offshore):
26020ST.OO.DD001IN.02.A (I think it cost around $25k)

26238CE.OO.1300CE.01 ($96k on website)

26420SO.OO.A600CA.01 ($47k on website)

26470OR.OO.A002CR.01.A ($40k)

He will definitely get something for his wife. What else would be a good path for him to get 15416CD.OO.1225CD.01 (I've heard it's usually the 9th allocation from AP).
