I ended up taking first in the Cache Refresh Stimhack tournament hosted by @fightingwalloon, and this Kim deck, as well as Kim himself, were the main reasons for my success, going a nice 7-2. This tournament featured heavy sideboarding, but this decklist is what I would take to prepare for a field of varying decks. Once you've decided to play Reg Kim, your cards are going to look mostly like this, so I'll write a bit about how I settled on Kim.
Going into the tournament, while I was thinking of strong corp deck options, I noticed that most key pieces to Fiery SYNC were available, and knew that deck would be prevalent and important to beat. While building sample decks I also noticed how many draw cards I usually rely on are unavailable (no Earthrise, Inject, Street Peddler, Quality Time, even Patron); whatever I was building needed room for Aaron, a broken card that helps with both of these problems. He's in faction for Criminal (and extra Boom! tech in On the Lam), so I started trying to make a deck there first, but ultimately their lack of additional card draw options, only 1-of Desperado, only 2-of Account Siphon, were troubling enough that I looked for alternatives.
Obelus is a great card; like Aaron, it helps with card draw and keeps you from being killed after HHN, though not 24/7. It's a lot better card than On the Lam in other matchups as well. For identity I looked at Omar first; he offers great pressure from the start of the game, and can roll with any deluxe box, which gives you more options. I don't think he's a bad option, but with my focus on beating SYNC, Kim's ability to trash operations and 1 link are worth being locked into O&C. I kinda want I've Had Worse anyway, as another broken card that helps draw more broken cards. I think I made the right choice - I trashed Hedge Fund, IPO, 24/7, Hard-Hitting News, Friends in High Places, Biotic Labor, and Archived Memories with his ID ability in the tournament, often through single accesses with Temüjin Contract and/or Datasucker. Unlike every other ID, you actually want to access operations, so every access is more valuable.
After a few rounds bending over backwards to fit in two Aarons, I decided on this influence spread with Citadel Sanctuary as backup. It works nicely with Kim's link, and was critical in the semi-finals to give me TJC money through a Data Raven each turn.
The matches I lost were to Boom SYNC and glacier HB with Biotic back-up (this came down to the last card in R&D!). Both were close, and I had a chance to win, so I credit fully the skills of my opponents in those results, and I know that had I played better I could have made it happen. My wins were against a lot of varying types of NBN, so I'm very happy with my deck choice (though none of them were certain wins - game one of the semis, again, came down to the last card in R&D!); in the finals, I (in another extremely close match) beat the same glacier HB in a unique situation that may have been a true stalemate. Due to a jinteki crash, we weren't able to play it out, but @internet_potato kindly conceded as he couldn't keep me out of his scoring remote and needed to IA to win.
I don't think there's anything else to add; I barely scraped into the top 4, so coming out in first is a really great feeling. I had a great time in the tournament with a lot of intense matches, so thanks to everyone I've played and fightingwalloon for hosting. I had a lot of fun deckbuilding for this, and think there's still a lot of viable deck builds to explore.
I'm curious why you only ran Spooned as opposed to Forked or Knifed? I have been out of the game for a while, but when I played Ed Kim was my favorite runner.
