Storz and bickel capsules
I can't recommend them enough, I have been using them for a few days now and I don't think i will go back to loading via stem again! I have been loading them with around .17g with a tamp...setting 9 with a good long draw they throw out Plumes of vapor...2 hits and the caps a nice even dark roast, it's definitely been hitting harder this way too bit of conduction going on with the metal if caps...give them a try!
