I have my first RBAs coming in, a Fogger V3, Taifun GT, Taifun GS, Kayfun 3.1. They should start arriving next week! 
As they are my firs rebuildable tanks (i only have experience on my 5 RDAs), i suspect i will need some practise before i get the setups right, you know, trying out different wick diameters, silica, cotton, mesh, etc. And these "experiments" are expensive in terms of e-juice wasted, "oops! its leaking!, take it apart, put a thicker wick in there", "dang! its dry, maybe remove some cotton?" you know the drill.
So i was thinking i could use someting instead of ejuice that is cheaper and i wouldnt mind wasting untill i get it right.
Of course it wouldnt have to taste good, or produce a ton of vapor, im only testing wicking. Just as long at it has a similar consistency to ejuice, and its not toxic, it should do fine.
What could i use instead of e-liquid to do this initial tests? i was thinking pure VG, but its a lot thicker that the liquids i normally use, wich are usually 70/30 PG/VG.
Any suggestions?
EDIT: im thinking VG is the way to go, but what can i use to cut it down and make it thinner? do i add water? how much?
