So... it's 1 week later.
The honey does seem to change a little over time, in a good way, but not very much change... it just seemed to get a little stronger, which I thought was the opposite of what I expected.
I have smoked only Killer Juice for the last week... pre-mixed Blueberry straight up in a big 6mL bottom coil glass tank on a mod... self-mixed blueberry+honey in a little 2mL tank on various eGo-ish batteries. basically the following which is listed for 30mL batches.
7mL of base (90% PG, 10% NIC)
1.5mL Blueberry Flavor
1.5mL Honey Flavor
20mL VG
I have a bit of a pre-steep system that some wouldn't like... but it was basically air-stone bubbled for 30 minutes while gently heated, which continued for about 2 hours, reaching 145F then removed from heat and capped. Yesterday I measured the NIC at 24mg/mL+/-2mg/mL.
In comparison, the pre-mixed BB would probably take 15-25% of the BB flavor to reproduce, but it's hard to tell given I don't add any PG to my mixes (right now). I have moved KJ's Blueberry to the top of my un-tainted BB roster! <-- Since BB is my favorite flavor and my ADV, that says a lot about how much I like blueberries. I never knew how much I liked blueberries until I started vaping, btw.
I don't kid myself though... I figure the KJ Blueberry Flavoring is a re-brand of a flavor by some 'big company'... I don't care, for all I know KJ has little fairy-vipers that spit tasty venom in their flavors late at night when everyone is sleeping... whatever makes it be #1 on my list is whatever it is and not my concern.
As a side note: The watermelon flavoring turned out to be exactly the type my 'way much better half' was looking for, however she is burned out on it right now.
If I had to sum up my experience in fewer words, perhaps a single sentence, it would be the following.
"Having tried a few of their juices AND a few of Killer Juices flavorings,.. I now appreciate and understand why they have a following."
