I think a variety of rush strategies are viable. I don't see a lot of Shaper, so I think FA (typically via Biotic) is strong as a close-out option.
So Midrange HB and Sleeper Hold are certainly viable. I've been having good luck rushing in Titan with the threat of Midseasons. I score GFI from the table regularly, but only when I have a large credit lead.
Both ICE and defensive upgrades are countered very strongly by Rumor Mill and Sifr. This makes scoring plans that rely on the runner being unable to access a card they know is an agenda is difficult to pull off. There are other scoring plans available.
