I totally agree, that is some of the cleanest tasting base I've experienced. It does take flavorings quite well, too. I got some small sample bottles a couple years ago with a mod purchase and it was nice, though wasn't really viable for regular use in my DIY due to price. I was willing to put up with the slight "peppery" taste of other nic bases in compromise, I found others that flavorings would pretty much completely mask once mixed that were far cheaper. If I were to vape unflavored, though, that one is definitely a good choice
I don't DIY at all anymore, though, kinda lost interest when all my favorite flavorings became unavailable or difficult/expensive to acquire. I didn't feel like going through the arduous process all over again of sampling different flavoring sources and then trying to find the optimal mixes for each flavor that showed promise. I went through that process once and was extremely satisfied with what I was using, but then that all went to hell. I've just been buying off-the-shelf juice from some time now
