I dilute sometimes with vodka .......
I use the wine - cooking analogy though ya know don't cook with it if you wouldn't drink it ........ so I dilute with Absolute Vodka

Me has no trouble drinking that !!
I've gone as high as 10% but that was back in the early days of 100% VG and cartomizers.
I haven't found the need to dilute anything in well over a year since I've been re-building.
Not sure what that juice is but I highly doubt its thicker than my Boba's Bounty ..... don't believe that is possible but maybe.
My only complaint with 100% VG juice now is when I'm out in the winter skiing or what-ever ..... after about 4 hours outside its a b*tch to squonk .... Dunno really ??
Silica or cotton ?? Maybe it likes the other better so try both.
