I'm in search of my perfect throat hit and want some advice before I prefer more. My local shop has good juice but it's expensive, like $8.99/15ml expensive. The first one I bought was 70/30 pg/vg 12mg nic and it had a nice throat. I then bought some 50/50 6mg nic, from bootleg and mount baker that have almost no throat hit. I went down on nicotine because I found I was vaping quite a bit and was noticing headaches but then lost the throat hit. Can someone point to a good guide or advise here. I'm curious as to the relationship between flavor (sweet vs. Creamy vs. Tobacco), vg/pg and nicotine content.

How long roughly should the juice stay good in its container if opened. Just want to gauge how many to buy at a time knowing I may be switching flavors fairly often.

Just wanted to get my first post our is the way. I'm a former smoker who quit 5-7 times and it just never stuck. Giving this a try so at the very least I don't smell like Crap. Started off with a Provari and kanger aerotank and like it so far. It's a little bulky for on the go so I may be leaving that one at home to drip then buying something more compact for on the go. Suggestions are welcome and I'll probably post the same question in the appropriate forum.
