I also came up with a great vape that I am loving right now. I like it so much I made a 60ml batch to last me until the order gets here! I am going to try the whipped cream in place of the condensed milk when the goods get here.

10% Cocoa
2% Condensed Milk (I have also used the sweet cream and it works well too)
2% Vanilla Tahity
1% Caramel
My version of a "Hopscotch"
10% Butterscotch
5% Caramel
2% sweet cream (fresh cream)
This one needs to sit for a little while, I find FA butterscotch is a little bitter right after mixing but is yummo after about a week.
There was a thread in the tips and tricks thread about speeding up steeping.
I heat up a coffee cup of water in the micro and get it pretty hot. I put my freshly mixed bottles in the hot water for 20ish minutes and it really helps to mix the pg/vg and the flavors.
I usually mix my juices 50/50 so my juice is a little thick, but I can vape the Cocoa mix right away after soaking the bottle it in the hot water.
