Thread: Confused Architect
Your second question really depends on your needs. ORE is the one major pain item to get since almost everything we make uses large quantities of it.
You may be better off surveying more to find that "sweet-spot" of ore, but if all you can find, and need the high stat ore, harvesting at 40% is worth it for a medium harvester. I wouldn't use a heavy since the increased BER isn't worth the increased redeed/maintenance cost for such a low concentration. (I only use heavies on concentrations over 50%).
Remember that unless you are crafting stations (which use high OQ Ore), the stats that are important are UT, SR and HR. OQ could be a 1 as far as most of our items care. And ALWAYS use lube oil for the chem unless you have a fiberplast/polimer with great UT/SR/HR stats, otherwise you will pull your final combines down too far and won't achieve maximum effectiveness.
