seems that wismec has discontinued them. there's a special edition with a finish I don't care for but none of the old plain stainless. 24's won't work on my pico. just got 3 serpent minis from gearbest, much too restricted airflow for me. wondering if opening up the slots would help or if need to drill out the main air channel. any reccomendations for airy rdas or rdtas single coil would also be welcome
