Hogie; How are you... !? Long time no "read", heee....
Let me say I guess the extra-wicking together with a sort of sub-chamber between the coil/ ceramic cup and the tank plate are the key components which may translate into the effectiveness behind tanks...
The extra wicking makes for a larger surface providing extra juice "available"/ 'ready' to compensate for possible wicking problems... Though, this also translates into a state of peripheral vaporization, so to speak: More vapor but not really GOOD-good vapor; more on the weaker side of the spectrum... Hence the flavor muting factor, possible lack of TH, etc... And the surprising factor and reputation of tanks to go through large amounts of juice and not really seem to be producing up to it. This, however, makes sense since the consistency and convenience factors may be the upside.
Playing with the level of the wicking fibers and mesh little roll inside the syringe may provide a more effective, powerful vape. OTOH, though, it seems obvious tanks are likely to get, eventually, very hard-to-draw, clogged up and under-performers, too fast too soon, at least for many of us... The larger wicking surface and chamber may generate further residues deposit, and their air channel is smaller (at least in 510-Ts; I do not remember eGos...), ONLY one hole, in the first place...
IMO, the best cleaning method is an alcohol bath and a mini-dry burn... This really seems to help, a lot. You can dry burn them straight, or you could always remove and re-insert the plate later on... The wicking fibers, though will eventually need to be replaced after a few cycles... (You could also mod them...)
Removing the plate is easy, cannot find any link right now as my connection is slow, as of right now, but you may be likely to find videos on how to do this; it is very simple. Otherwise, you could always dry burn directly after blowing the atty; eventually you'll see the glow...
While dry-burning is dangerous and should be considered an extreme intervension, I have found it is essential with these "rebel" atties...
And, last but not least: The 510-Ts works far far better in my opinion; possibly due to their shorter peripheral vaporization spectrum...
Hopes this helps...
