Juice blends, ratios and nic levels are more of an personal preference thing than an rba thing.
Finding "MY Preferred" VG/PG ratio is one of the most frustrating things a new vaper goes through, and usually just the first frustrating things about vape that happen along the Vape Trail
When it comes right down to it, once on the rba path, one learns how to wick, build and adjust accordingly, no matter what juice one prefers.
I quickly levitated to high VG juice, found High PG to harsh. Mix at 70-80 VG now. and use all recipies in both drip and tank rba's. Some juices will go through flavor, throat hit, and juiciness changes as ones watts vaped at increases. And as ones knowledge, skills, and inventiveness increases, will find that what once was viewed as Vape fraking out of you mind no way, becomes second nature.
Every one is different, so what is purrfect for me may be, like crap no way for you. And this is both the best and the worst part about vaping.
There is just so many ways to get ones vape on, and everything effects everything, every step along the vape process. So one issue or problem can come from a number of reasons. but all cause similar symptoms.
What I love about that, is once in understanding of whats going on, everything can be customized and tweaked to get the vape just for you. Can take vape as far or little as one wants. And trust me, the longer one vapes the more one's wants change and grow
The best advice given to any new member or person interested in vaping is sit back, get a beverage and vape of ones choosing, put on your reading glasses, check out all the sub forums about vape and become aware what is vape possible. The best vape decisions come from an informed position. But all have to start some where, and it is a very progressive hobby like any other sport or hobby enthusiast.
Most usually do drop their nic levels when dripping or vaping at high watt outputs. Reason being, get way over nic'd and a bit loopy when vapping that much nic delivery. I'm down to 12 mg, where used to be at 24. Many go down to 6 mg nic or 0, specially the big showboat cloud blowers, where that their primary focus.
Everything in vape also is very pertinent to what ones vape goals and future vape desires are.
Trust me, there's a lot more confusion to wade through before and clarity comes to mind, and that's when the fog sets in, or something like that.
Vape long and Prosper.!!!
