Unfortunately, it looks like there are only three of us talking about this, with our investment in the subject determined by where we have found ourselves in life. My only experience with discs is on a bike I rode on on a wonderful Irish tour a few years back. Long story, but the tour operator was kind and hospitable enough to modify one of his bikes with a cable splitter to run both cable discs off a single lever. Many hills, many fast descents, much rain, but all in all the trip of a lifetime. Since I usually ride a road bike, often in the mountains, I'm probably more particular on that set up, so I don't question gixer's desire for better balance. Long and short, all three of us are riding and loving an activity that may not have been designed for us, but still is so much better than not doing it.
