cosmic fog krypt is one of the lousy us juices. both in terms of smoothness, and also in terms of flavor.
i'm guessing you can't handle the throat hit for the us juices you've tried so far.
wait until you try high vg 3mg juices. (anything 70vg and above)
i've tried lots of malaysian juice, almost every popular flavor/brand. the taste is too artificial, they usually put way too much menthol in it, and wayyyyyy too much sweetener. however, the flavors are more immediate and you taste smell it the moment you vape it. the nicotine level is also garbage. most contain next to no nic, and some contain very poor quality nic. i've vaped 1/4 tank of a msian juice and gotten a minor headache from it.
for the good us juices, the flavors are usually subtle and underlying.
people like msian juice because it's like that char kway teow that's overly salty and everyone who's used to salty-msg-food likes it. us juice is like that truffle infused mushroom risotto that some people will feel is an over-expensive thick angmoh porridge.
i do vape on msian juices occasionally, as i find a few are alright. actually, aj mango blackcurrant does have a fairly strong blackcurrant flavor. if you've not tried horny mango, get a bottle of it. smell it before you vape it. i believe the mango flavor they use is probably from the same brand. once you do a comparison in smell/vape you'll realize that the blackcurrant is actually not as invisible as you believed. it also has something to do with the way you vape.
the way i do it is i exhale from my nose at least 30% or more of the vapor before i exhale the rest from my mouth. this lets me smell the juice better - and taste is largely derived from smell. once you start doing that you realize that your juices get more interesting. you'll definitely smell the bc for aj mango bc this way.
