I too am mystified. On another forum I check out regularly, but am not a member of, there is a fellow who did what he called a "Brylon Challenge". Following the posts, it appears that his experience was far more pleasant than one would expect. I believe he used a Yello-Bole, and actually got good results with it. To me it's all ???, but the market dictates. Some people must actually enjoy them, so to each their own. Hell, look at our own debates about Mixture 79. It's still going strong, but many a well-loved blend has long since gone by the boards.
