Queen Euphoria, Missing Blood, or Double Exposure?, Introducing insect spirits to the campaign (spoilers) Options

[Abstruse]

I'm running a Shadowrun 3rd Edition game and only one of the two players knows a lot about the Shadowrun world and even then, his knowledge is rusty or lacking in some areas. I've set the game in early 2055 with the intention of getting the players in Chicago by August 22, 2055 (yeah, that). The plan is to run a mini-campaign that involves them trying to get out of Chicago and back to Seattle.

In order to set this up, I want to introduce the insect spirits to the game, but I'm not sure the best way to go about it. The player familiar with Shadowrun knows about the Universal Brotherhood-Insect Spirit link, but the new player doesn't. I can't make up my mind, so I'm going to throw this to the hivemind (no pun intended) of Dumpshock to help me mull it over.

Missing Blood - Pros: Interesting story. Very Lovecraftian. There's an insect spirit baby, which is just creepily awesome. Cons: One player already knows UB = Bugs and that spoils the mystery.

Queen Euphoria - Pros: Bugs will be a surprise to both players. They just finished Dreamchipper so they'll think I'm running a media-based campaign considering (I also have Mercurial, Total Eclipse, and One Stage Before books I can leave laying around for misdirection). Cons: This adventure has always felt "weak" to me. Doesn't set up the big plot very much other than introducing the bugs.

Double Exposure - Pros: I really, really like this adventure and have the perfect blackmail ready for the players. The UB connection is buried and I've got misdirection all ready for the knowledgeable player if necessary ("But the Universal Brotherhood doesn't have extraterritoriality and the Project Hope camps do."), so long as I don't get too heavy-handed with it. Cons: This is more of the big final set piece before the finale rather than the starting point.

I could also try to write something myself, but something tells me that I'm not quite going to match Findley in terms of plotting and pacing.

So who's run any of these? Any opinions?
