I love you ladies! Post successfully removed, wick reduced by a couple of threads-worth, GSH4 vaping beautifully. So I now have enough clearos to last me months even with my tendency to drop & crack them, with a handful of old CE4s still in use plus about 11 GSH2s 
Gin/Ledaire, I found the Hangsen Pineapple seemed OK for the tanks, been using the same tank for it for about a month & it only cracked when I did my usual dropping it on an uncarpeted floor.
