This is an interesting and educational thread, in that, at least two very experienced roasters/consumers have made the point that taste preference is an individual thing, it evolves with thoughtful tasting and there are a number of variables beyond roast. I tend to prefer a full city to a full city + roast depending on the bean variety. But one of the things I like most about coffee is the process of experimenting to find a great cup for you. I'm currently trying a new PNG bean and started with the full city, will next try the full city+ and may end up blending the two. One of my favorites with another origin is a 50/50 blend of the two roasts. Like food or wine, experiencing different tastes is a big part of the enjoyment for me. Of course, if you're running a coffee business that's a whole different problem and I guess what the "crowd" thinks matters.
