I'd tried quite a few max vg juice over time, alot of them are anemic or thin tasting, lack depth and flavor. Smooth, yeah I guess...I can't even feel the vapor going into my lungs with some of them. I like throat hit! So in the end I just keep going back to 50/50...just works best for me and my tanks, from squapes and kayfuns up to rebuildable tanks and subtanks.
What does bug the hell of me is like you said, alot of these companies never even post the ratio on their sites, and the only clue you have is the nic level, 3 or 6 mg. I guess if all you know is dripping....but that's kind of arrogant. And I've emailed quite a few with polite letters asking if they'd consider a 50/50 offering and usually I never get a reply back. Or I'll be told something like "Our higher VG blends do tank quite well with subtanks". Maybe so, on a Freemax Starre or Uwell Crown...maybe. I see tons of juice companies sponsored on say, Vapers.tv, seems like almost all of them are high vg juices.
In our town we have 3 vape shops, all of which carry very few 50/50 blends. Once I went into a local shop with a Kayfun V4, and the guy behind the counter asked me what kind of tank that was, he'd never seen one before. C'mon, I mean a kayfun isn't something that exotic! But I guess if you hadn't seen a kayfun or squape or Billow V2, you wouldn't have much use for 50/50 juice.
