I made the switch over to SS316L over a year ago, and the need to change builds dropped. I have one tank with the same build for 11 months...I put it in on my Vape Anniversary in March of 2016. I'll pull the wick when the flavor mutes, fire up the coils and rinse them, then fire again and use a small SS brush to clean the soot...then fire one more time and final rinse. It's still as good as it was the day I put it in. I won't pull it and rebuild til it finally dies off. The tank is the Aromamizer Supreme.
I have a second Supreme that I'll screw around with when the feeling hits me, and it's had a number of different builds run through the deck.
I just picked up the Aromamizer Plus, and am now searching for the right build to match my needs. Once I hit that level of happiness, I'll likely rarely mess with it, only cleaning when needed.
I'm the same way with my RDAs...only rebuilding when the coils are roached or I'm trying a new build.
There are some real artists out there that will build, heat, take photos, then pull the build and do another one...it's a hobby for them that I respect. There's no way these old eyes can focus on anything that small, so I just stick with basic single strand, double coil, simple wrap builds. I build for personal vaping satisfaction...those folks do it as an artform.
