The way I see it, you have 3 flex influence for match-ups: 2 from Clot, and 1 from PolOp (from @kiv's list).
So, it's really a meta call on which match-up's to shore up. I cover it in the description of my list, but I'll put it here as well:
On the Lam - Best way to deal with Accelerated BOOM! combo, which was pretty common in this area this SC season. Also, helps against Breaking News EoI, Mushin Overwriter, and Ronin. This was the slot for Clot, but I was expecting more degenerate Corps, than FA Corps.
Basically, I was expecting a lot of Railgun and CI7 at the top tables, that's why I included On the Lam and Eden Shard.
Aaron is a fine choice. The problem I see with him in Spy Hayley is that you need him out early to take advantage of him. You need access to at least 2 copies, and that makes it tough on influence. I have briefly tried on copy of Aaron and one Hostage (which also helps get the last Trader if you don't need Aaron early), and that's been promising. But, I had to cut one Camera to fit it in.
Which current would you worry about? Targeted Marketing is the only one is a problem that I can think of, and you're not likely to win a current battle against Sol. You can still win with this deck if you let the Corp have lots of credits, you'll still have a lot as well.
Midseason is not a concern. I chose this deck to have a good match-up against a rushy Blue Sun deck that can often get to 30+ credits in the first few turns. They can usually get to 4-5 points before you can beat the Midseason, but then they cannot score anymore. Film Critic will only be useful (for now) for TFP and Haarpsichord, which I don't see often. TFP may be a concern if you're seeing a lot of RP or IG Prison.
TL/DR - Basically the deck has a few flex spots and influence that can help against most problem match-ups, but there's not enough of them to have a good match-up against all decks. Choose wisely.
