Yeah,i don't either.I used to make a bunch of Bill's stuff which is mostly 30%,but now,any of them i still use,i cut in half.

I know ... I choked when I read the %'s in his recipes.

I tried just mixing up the flavors alone, nothing else, and then adding that as my flavoring, but,

.
We also bumped heads about "steeping".
Too me, unless I make a fresh
juice to vape for the day, they are going to sit and steep anyway, which is going to change them .. at least it does for me.
Also, making a juice for the day won't work for me, because I vape 9 different flavors in 9 different mods strategically placed around the house where I spend most of my time.
Those flavors change again when refills are needed.... yeah, I like variety ... favorites yes, but no ADV's for me.
So I have a lot of small batches of flavors mixed that can't help but "sit" for a while.
Bill also didn't care for tobacco's, but I haven't found one yet that didn't need steep time to taste it's best.
BTY, I do like using some FW flavorings in simple recipes (not solo), like Yellow Cake, Biscotti, Bavarian Cream, and the Whipped and Sweet Creams
but, all in all, I probably have more TFA than any other flavoring.
