These conversations about engineering and experimental additions are just leaving me confused.
I suspect that the "pre-engineered" drives gained from the Sol CG are slightly better from the ones you can "purchase" from Human Tech Brokers.
I had believed they are identical.
Apparently, these conversations had me a bit confused as well. I missed that @Frankymole had been talking about the mass produced SCO drives, not the tech broker drive. My thanks to @Spaceman-FXL5 for the clarification.
