I may be wrong about that, and it's bad for me to say it since i have no factual evidence to support that claim, just something I heard from a random person on the internet, which has zero credibility probably.
There have been a couple of Vape Dudes flavors that I absolutely LOVE. I've never tried EC Blends. My buds are still recovering, so there is that, too, and this last week ALL of my flavors have been hit or miss, and some of the things I've tasted my tongue has totally confused. I haven't seen anyone here using them, but there are a couple of flavors out of Chi-Town Vapers that I like - one enough that I order REGULARLY, and some from Better Vapes - smallish online store, but they also have a storefront a couple towns over from us. The main one we get from them, that we BOTH vape, after the first bottle, after we found out that THEY made the juice the other store carried, we decided to get an extra flavor shot on the 618.
Definitely go into a storefront that has a large sample size for you to taste from (the samples SHOULD have a lowered nic content on them, so you don't get sick from sampling too much - you know how you feel when you've smoked too much; that's how it feels when you vape too much nic) to get an idea what you might like, at least of what they carry, and go forth from there.
Yeah, the higher PG can be pretty harsh. I've always started out on 50/50 mix unless the manufacturer recommends differently for that particular juice. That way you get equal parts throat hit/flavor and vapor. And then work up or down as you see fit. I myself wouldn't want to go below 50 on PG, though, because you lose flavor, but running 90, even 80 pg newly, and you are still smoking analogs, I can see it being a bit harsh.
The peppery feeling could be you actually inhaling some juice that got into your feeder tube - at least, that's what I've heard it described as. What flavor juice was this?
And like Tam said, the FIRST thing to try, if it feels too harsh, it try to dial down the voltage in your twist. Been finding that out by trial and error since my variable voltage came in at the end of last week, well, a week ago Friday, I guess.
And I would recommend switching to glass tanks as well - I like both Davide and Kanger Pro Tank 2's (and pro tank mini's), but I still have some evods on hand for sampling (but some kanger mini protank 2's with replaceable drip tips are going on my christmas list to replace the evods). The taste you get out of a glass tank is so much - well, it tastes so much better. And for me, bottom coils (like evods) taste better than top coils (like I THINK the Vivi Nova), IMHO, plus, you don't have to worry about storing them on their sides to make sure the wicks stay wet, and you can let the levels get farther down before topping off, since the coil/wick assembly is on the bottom.
But one thing....especially once you find a COUPLE of flavors at least that like, try not to run the same flavor all day every day. It's supposed to make it easier for your tongue to, I guess, adjust?
So I am very new to vaping, but here's a brief history of my vaping experience. A couple of weeks ago I ordered an ego twist battery with viva nova tank. The first 2 juices I tried were made by Totally Wicked (they have a local store near me) and I purchased both their menthol and strawberry juices. Both taste fine, but they were INSANELY harsh on my throat. I did some research, and found out their juices are more PG based than VG.
So I went online to EC blends, since they offer the ability to adjust pg/vg, and ordered 4 new flavors. I received the package yesterday and have been vaping a great juice by them called "Chocolate Mint Crunch," All I can say is WOW, this juice is superb.
However, I have been vaping nothing but that since I received the package. Now, I am starting to not taste the well pronounced flavors I tasted when I first loaded up my viva nova. I figured I should switch to a new flavor just to give my taste buds a change for a little bit.
BUT, I have a question. My viva nova still has about 1.4 ml of juice in it. Should I save this juice, or just throw it out? I hate to waste a perfectly fine product, but is it still any good for me to use?
Also, how often do most of yall switch up flavors?
