Ya, what I mention about Dragon Fruit has nothing to do with hardware, or sweetener (As I don't use any). It happens the same in any/all hardware, in VERY short order, yet no other flavors do that from their lineup.
And I'm using all hardware I rebuild, so it's not like I'm complaining because it's crap hardware, nor is it happening just because it's faulty hardware. It's stuff I use and rebuild daily, and I ONLY have problems with that flavor (Or others known to do similar things of course)
So yes, same failure instantly with Dragon Fruit, in multiple (ANY) hardware (RBA's, Drippers, Clearo's, Nova's, carto's ect), without sweetener and it's 100% replicable every time. If you lower the percentage or increase PG to thin it out, then it'll take longer to happen, but that initial roasting flavor that starts it lets you know soon enough it's coming no matter what you do. Flavor amount on that one doesn't matter either, 3-5% where it's so light you can't taste it, or 10%+ and it's gonna happen in a hurry.
There is something in "Some" of their flavors that just burns way to quickly, like you'd find and expect in some other brands darker or super sweet flavors. And were talking about clear or near clear liquids, not overly sweetened (None in my cases), and fruits at that which are generally some of the easiest on hardware.
For comparison TFA Dragon Fruit doesn't do that at all, even if you use an unvapeable amount to where the flavor blows your head off
There's something in there in "some" flavors that they either add for sweetening effect, or already there and known and they want to leave it for some reason, or it's something that's not being properly filtered out for whatever reason. It's only certain ones, like I'm sure you'd find some with any brand, except with Flavor West it seems to be affecting some of the more clear flavors that you wouldn't normally expect to be affected by this type of thing.
I will admit, some of the flavors Hoschman mentions I'd expect might clog or burn easier than others, but that's just my thoughts by looking at the names I've never tried the flavors.
Goji Berry, Tropical Punch, Ginger Ale, Whipped Cream, and Cheesecake I would not expect this from so I was surprised to see those mentioned. The only one I have though is Whipped Cream, and I haven;t used it much yet so I've not personally ran into the issue with this one yet, but I'm sure I will since he's mentioned it as being guilty of this issue. I did plan to get their Cheesecake next time, so I'm sure I'll find out about that one soon too.
Coumarin Pipe, have you tried that Hoschman? Just curious, because it's on my get next list too, and I was thinking it might be a clogger as well but still wanted to test it out. BTW thanks for your testing info on Whipped Cream, sounds like it lasts WAY longer than Dragon Fruit! That Dragon Fruit is so bad you can't even vape a ml in a tank, not even sure what I could do with it! I see it's ruining some of MBV's other juices they use it in too, just look at the comments on Albino Drake! I doubt I'll ever use Whipped Cream straight, or at 10% or above, so it should be OK for me. I mainly got it as a mixer, and only have that 10% mixed up as an initial flavor test batch, I'll more than likely be using it at 3-6% in DIY combo's
Also, I forgot to mention previously, better add Salted Carmel to your list too!
