My top 2 juices:
Halo's Prime15
neutral sweet flavor; like any Halo's juices, very clean/clear juice. easy on cartos and great for all day vaping
BackwoodsBrew's Hazelnut tobacco
the kind of tobacco flavor i like with sweet hazelnut undertones. in terms of polluting cartos it's just like any other juice, not the worst but not the cleanest
I'm vaping almost exclusively these two juices now.
I really loved VapeRite's Hazelnut with naturally extracted tobacco, best flavor ever imo, but it kills cartos within couple of hours, so no go.
Started vaping at 18mg nicotine level a while ago. Been vaping 12mg nicotine for most part, recently decreased nicotine levels to 6mg and below. Now 6mg seems as strong as 12mg before and I think it's a bit too much for my liking. Past couple of weeks been diluting juice to 4-5mg's with which i still get a nicotine kick in my head. Next week going to start diluting to 3mg's. Tried 0 nic juice and it didin't give or do anything, kind of pointless, if it would have provided a throat hit with no nic i'd be vaping that, unfortunately it felt like vaping warm air.
