While we await Wingy's response to his cryptic and tantalizing post...... how about some more engineering discussion?

I unlocked Marco Gwent last night and really didn't know which mods to go for. I was in the Python when I arrived, and added stripped to the power plant and made the power distributor charge enhanced. None of the other options seemed worthwhile to go for. Which PD mod do you guys prefer? Is it ship-dependent for you?
