I use Perfection, Hand of the Gods, Immersion, Epiphany, Innovation, Determination, Masterpiece, Tender Touch, and a couple others (Culmination? Grandmastery?)...idr what on Weaver for my HQ attempts...consistantly get 80% HQ chance or higher on the highest level synths using all HQ materials. Anything 40 and below I consistantly get 1000 quality (or damn near close to it...950+) I'd say for 30 and below...I don't even bother using HQ mats to try and HQ anymore. It is just too easy.
