Aal, you are absolutely right on juices. I've been DIY for quite some time as dev juices for the multitude of tests and subjects I've had to work with. Liquid variation can have profound effects on performance. Far more than the average user is aware. To add to this…I stand by my often repeated impressions that the combination of a properly oxidized K-A1 t.m.c. and Nextel offer the broadest most expressive vaporization I've encountered. The growing number of subjects I've worked with continue to validate my own observations. Consequently I finally started to convert the bulk of my collection to Nextel/tmc operation last year. I still prefer some tabs and others on alt's like twisted or spaced and include rayon in the mix on occasion. But given the intensity and integrity to flavor, volume of vapor for power and sheer easy as sh!!t maintenance requirement for ceramic braid, I had to go with it. Too many mods at this point to avoid just having that great vape. The remainder, about a half dozen, KGD or alt when the bug strikes. We've come a long way in 3 years Aal, all of us. Fingers crossed for this community. Best of luck!
