I have triples on most of my bikes and I do the vast majority of my riding with the middle ring. I generally don't shift to the big ring unless I'm about to spin out the middle ring (which typically means I'm going down hill, because 42-13 will get me 25 mph), and I only shift to the small ring when I'm about to hit a steep climb. Besides, downtube shifters give me a tactile/visual reminder of when I'm hitting the extremes. I feel OK with this the way it is now.
