It turns out that e3 Feedback Implants is often the inferior option if the ICE otherwise lacks ETR subroutines to break. ABR allows me a workaround for such circumstances.
May replace Equivocation for a second copy of ABR instead. It's only ever ended up face-down fodder. But having access to a third Medium-esque card is also Really Nice...
Infiltration means never having to blind-check that remote. Turned out to be crucial deciders, oddly enough.
