I'd like opinions on who has the best chocolate juice. I've been trying out various flavors in cartos, and neither my runaway favorite nor my runner-up is available in juice, only cartos. The ones I've tried that are also sold as juice have been either too thin (as in not complex enough) or too harsh. I'm most interested in straight chocolate, though I'm open to those with undertones of other flavors (I was underwhelmed by a chocolate-macadamia nut that I tried, though). What are your favorites?
