The most mango-like flavor I've got in my homebrew, hands down, has been from whirlpooling Mosaic and Citra together at around 170F. This combo was so evocative of mango for me that I renamed the beer "mango pale ale" after the fact, to help guests get a feel for what to expect.
I've also tried this combo as a dry hop, and it was good, but not really mango-like IMO.
