I don't like the Notoriety/QC angle (in general, and there's no particularly compelling reason to like it much better in Sil), but if you can get into HQ reasonably the exposes are really nice against Glacier, especially since there's usually agendas you'd rather not steal (hello, NAPD) and ones you don't want to let them score.
Of course, getting into HQ reasonably (and repeatedly) can definitely be a challenge, especially in those later phases when Glacier actually wants to score. Feint isn't a real option (because then you could have been playing Infiltration in the slot and you're not properly leveraging her ability) - in my search for a repeatable answer, the best I've come up so far are Pheromones (possibly paired with a Sneakdoor). Of course, that's a ton of memory, so you're stuck either playing BOX-E or Grimoire (no space for memchips, since you're 40 cards).
In testing, this has so far been surprisingly un-horrible. Probably not Tier 1 for all matchups, but better than it sounds initially.
