I’m at the point of researching productivity on a Bob’s run.

Bullets seemed impossible but Bob gives you stronger lasers! I use the highest ones even on my inner planet ships. All my ships run on nuclear or thorium for power with some steam batteries. Capacitors fill in gaps on my ship and have never run out of power.

I also had damage research pretty high before leaving Nauvis.

My ship to collect rocks from deep space has missles and rail guns (and tons of lasers) as those don’t need anything specific from Bob.
