I've made RSO with trim that was every bit as good as RSO from bud. I freeze fresh trim until I'm ready to use it - then I let is dry, spread out on a flat surface for 2-3 days before starting the process of making RSO. You could do the same with fresh trim and bud, or cured bud. But I've never tried to make RSO with undried, fresh trim or bud so I don't know if that works or not?
