I vape mostly unflavoured 90/10 VG/Water for almost 1.5 years now, nic varies between 6 and 24 depending on device and mood. I just like the taste of diluted raw nic base, but the differences between suppliers is quite large. Some are simply disgusting and go right into the bin (mostly because of slight chemical taste), some are too flavourless and remind me of a steamy shower cabin (but with a throat hit), while others are just great with a natural and earthy taste that never bores me.
