I really like the Phoenix atty too. Silica has an advantage over cotton when it comes to changing flavors. You can dry burn to get rid of previous flavor. I rinse the coil with water, use a paper towel to remove as much moisture as I can then dry burn in front of a fan. I can go from a menthol to Gorilla
juice this way without making a new wick/coil. It's a very handy feature. I use 3mm wick a bit over an inch long. Rather tucking the legs down in the
juice well I fold them upwards when screwing the body on. I've never had any wicking or leaking issues. I carry it in my pocket all day every day.
