Go easy on the flavoring, you can always add more, but it's even harder to dilute!
Just learned a new tip (for me!!). Put a drop or two of flavor in a little coolwhip (1 tsp or so?) to taste your flavors. Don't have to waste pg/vg/whatever. Also can taste with a drop or two in a little water.
yes I do easy as pie...By the "base" do you mean the nic, PG and VG? Then add whatever flavor later?
But a 30 ml of DIYFS HOLY HOLY GRAIL RY4 at 13% NEVER fails me! <= best tip I could ever give ya'!
