Casey Jones doesn't wick either.
weird. My DIY is 75% VG and it wicks fine. I wonder why the two above juices are so viscous?
From what I have learned via their fb and website is that at least for ITC, the source of their vg is naturally extra viscous. Which isnt a problem for me, as I tank their 50/50 which is now a 60/40 pg/vg (but wicks like other companies 50/50) and drip max vg. Then with lots of companies esp some of the giant vapes type brands that I also vape, it will say 70vg but seems so thin which I tend to attribute to a aqueous vg type calculation. Aqueous max vg types do provide pretty comparable vapor while they tend to wick better, but the thinner the messier when I am putting it into drippers. Hope I made some sense.
