All good questions/comments! I feel like maybe you put more thought into your response than I did in my post
re: breaker suite- my point was mainly that since stimshop takes up a bunch of slots and stealth takes up a bunch of slots, maybe 1 stealth breaker and the rest standard would be reasonable-- then you rely on smoke, Net Mercur, and maybe a cloak to fill in on stealth credits (and Cold Reading in a pinch). The traditional stimshop builds use hw/programs with high install costs which you cheat out with stimhack credits, which is why I went towards gordian.
re: comparison to Nexus Kate, I’m not really sure. On the one hand, bad pub is awesome for stimshop, and Net Mercur can be thought of as a pseudo bad-pub. On the other hand, if you were to replace Cold Reading with Modded you can get bigger install discounts with Kate (plus that 5th link that makes nexus so tasty), and maybe not have to monkey around with the whole workshop thing.
I could see smoke + NM + PW being potentially a 1 credit-per-click discount on hw/programs vs. Kate’s 1 credit-per-turn discount, but it’s not super cut-and-dry.
My thought process was “Smoke + Net Mercur ~= bad pub. Bad pub is good with PW. Credits that must be spent during a run are good with PW. Cold Reading is credits that must be spent during a run. PW likes expensive hardware. Security Nexus is expensive.”
Whether that actually adds up to a coherent deck is not at all obvious to me, but it seems neat.
