When I go about building a Wong crew, I find myself rarely having stones for Swine-cursed.
Wong really wants Sammy, McTavish/Lazarus, Cranky and Trixie.
Without Sammy, you can't take A Gremlin's Luck, which greatly reduce's Wong's threat.
Without McTavish, you are missing the key offense of the crew.
Without Trixie, you can't position McTavish as easily, you don't have the awesome scheme dropping powers, and you don't have initiative cheat, which is amazing for a blaster.
