I saw that too.  I have never done it with any Super-T spring though, have never felt the need.  It would surely be a good thing to do if I were into maintaining things, but one of the things I've always valued about my Super-T mods is that I can pretty much neglect and ignore them. 

 One thing for certain, the lower ohms you like to vape with the more maintenance you need to do on any mod.  Since I can get more than what I need at >= 1 ohm I can get away with quite a bit of slovenliness.
