When using a rosin press for real high quality trim like sugar leaf and smaller nugs, would putting the material directly into a press yield higher than running it through bubblebags first, then pressing the bubblehash?
Smalls are worth pressing if you have the capacity. Trim needs to be quite clean to be worth it. I've pressed nasty black tar oil at 5% and golden tasty sweetness at 15%, material quality means everything.
