Well, with a VG based juice like the one your smoking it's going to be sweet, but if you use a 60 pg / 40 vg you wont get the intense clouds (well not by much) but the flavor will come through great and wont be as sweet as the VG.
If I were you simply try a 60 pg / 40 vg blend.
If this suites you stick with it if not try a 50 / 50 and go with companies like ;
Five Pawns
Cosmic Fog
Fuzion etc.
Experimenting is the only way you'll find anything out to work for you, personally.
Brendan.M got a reaction from Mplough in Vaping too sweet?
