This is a great question but better directed at the crowd in the Persei vape thread. As for the 8 questions. To belief it can do bubble and dry. A few other concentrates as well. Exactly what isnt yet known. As it will be variable temp it can use different things...broad. Persei is a great unit. Very well functioning, the crew knows the science, they have the drive, it will continue to flourish. As for oil hating, Persei can use a variety of concentrates, and for future, flowers as well. BUT, anything that cannot melt fully cannot currently be used via Persei. Now about the atmos. No hate, buttt... just read the persei thread. It explains why the units are as they are, and why they ARENT like the atmos. If you like the atmos look, go for the omicron with the universe attachment (to be released). Its smaller and does its function. Persei is the Poppa bear. Persei will get all the attachments. Maybe you will enjoy oils someday. And maybe someday someone will decide to do the gas chromatographic work on BHO and tell 100% whats in a normally prepared batch (meaning, proper without bells and whistles though) and clear any worries in many peoples minds. until then, they vape. No one can truly tell what the 8 will be like, as it is getting a redesign. Even G may not know, and he knows all! But if you want discrete, go omicron and for flower get the universe attachment. OR Persei Matte black with the stealth SS upgrade with smaller battery tube and the 8 for the flowers and bubble. Not ophos familiar. but cant be too different of the sorts. smaller. microscopic possibly. Personal vote, Persei. Its got all the goods.
