Of the two options that currently seem the most popular (2 and 4) I would probably go with 4. Of the options there I would think it might be fun for you to work for the FOW, only because they're old and stuff and rich, and probably are into some pretty weird stuff. Then again, the Strangelight Workshop is pretty much tailor-made for "adventuring," with its focues on the strangely arcane and bizarre. Is an X-Files/Ghostbusters type game something you could get behind? If so, people might want to reconsider their skill choices a bit, to fit that line of business a bit more.
What do IK monster hunters need in terms of skills? I'm not talking about the prestige class from MN1 here, mind you.
