Thanks for your thoughts and suggestions. I could be missing something but doesn't the Reaper have a wide internal diameter chimney to cater for the higher airflow deck which makes it more of a DL tank? Looks like it would behave similar to an (older) Augvape Merlin which wicks like a champ if you want to run high watts (I don't) but the vape density is lost somewhat in the wide chimney as it's not a proper MTL tank. I'm looking to see if there's something out there with a difference in vape quality but not at the expense of a glass tank though; my ADV has killed all plastic tanks in its path. I know very little about Ultem but my spidey senses are tingling that Pyrex and 316 SS would fare better long term. Part of me would actually be pleased if there isn't a better tank for my setup.
