Well, the way I look at it, the build isn't running yet when you reach the caves. I think you need a certain critical mass of offensive utilities before they suddenly become godlike, and I'm finding that this happens around -2.
I just had an unsuccessful run (for once):

I was 4 steps from the exit (roughly 2 turns), but this time, luck was not on my side.
I farmed Testing quite thoroughly, but I think I stayed a little too long. I was out of good weapons when I progressed to Access, and could never stabilise. I was forced to use energy weapons, which required a lot of heat sinks, which reduced my offensive capabilities. I was also taking more damage because I couldn't oneshot enemies, and thus I was absorbing a lot of heat from thermal damage.
This game, I tried the opposite of a propulsion stack
. I am not sure how effective it was. While I had armour, the build was monstrous, but I ran out during Testing.
I also enjoy these discussions on strategy.
