(I am NOT talking about the regular EGO tanks here -these are a different cartridge that I found on litegicusa.net) Has anyone tried these? I read reviews on the litecigusa.net site and a few c/o poor wicking ability and filler issues. If any of you have tried them, would it be possible to remove the filler that comes in them without breaking the baffle and replacing the filler with maybe some of the blue foam filler instead, which is supposed to wick better,etc...? If I could mod them to fix that issue, it sounds like they might be perfect for me to use with a regular 510 atty on my EGO battery.
