Voted for B for this particular set.
On the note of 'particular set' though... I'd really, REALLY like to see more in the way of jet packs in the future for costume pieces. Not powers or anything else, just costume bits ranging from retro sci-fi to ultra-high tech and even fixed wings and hover packs.
There's too many examples throughout superherodom and other fiction, it's kinda a blatant missing option in the game. (Even seeing some of the current in-game jet packs as costume pieces would be great, like the raptor pack.)
