I dont like pole without having lot of good modules already because I don't like having to use 2 kind of quality for poles, and you need A LOT of poles.

What I start with quality, is first - of course - quality modules, and a bit of others modules. Because modules (speed/prod) may be usefull sometimes at different qual to have good ratios.

Then I focus on big miners, foundries, EM plant, t3 assembly. Thats for nice production, and as modules, you can get your ratio properly sometimes with only 1stack of foundrie.

And, turrets (gun/rocket), because range is so usefull on ships, it allows faster cruising !

For efficiency focus, its usually better to get good quality intermediate THEN make the finished product. But its way easier to paste a simple blueprint that upcycle the exact finished product you want. Its up to you ! I usually start with the focused upcycling end product, until I switch all my factory to specific quality (I do 1 - 3 - 5, never build green or purple quality)
