Alright so I have some suggestions. 1. You never need to produce materials at that sector, just use a launch sector 2. For med/low threats just launch with a core schem that has a surge Swarmer with overdrive projector, some walls and like 2 menders
Create a core schem with a pre-made defense and poly production, make sure the core launches are full of resources and go straight manufacturing t4 or t5 units and destroy enemy cores asap or unless if want to have fun you can prolong it as you see fit.
