I use Boge 3.0 and notice that most of the darker tasty juices don't work well at all. I really like vermillion River Caramel Capp but alas I can't get it to work out in a carto. How sad for me. Anyone else find any caramel or coffee juices that do work in a carto? Anyone have any quick fix ideas or things that work for them? Maybe a different combo of pg and vg in the liquids?
