I've found that both of those work really well in carto tanks. Getting the juice to soak into the carto filler the first time takes a little patience, but after that it's just refill the tank and go! Considering how thick they are, I was surprised how well they worked, but then again those two juices surprised me in a lot of ways . . . I don't like tobacco flavored juices, but I instantly loved those ;-)
That's good to know, Killjoy. I really didn't think it would work... but I guess I was just too impatient. I'll give it another try.
