That makes sense. It's a bit of a side topic, but lowering bars is not only to reduce wind resistance, it also takes some of the weight off your rear. When people new to long distance cycling presume that they will be more comfortable the more upright they are, they are mistaken.
Anyhow I've been experimenting with fit a bit on my B17 equipped PX10, which is set up as a touring bike. At the moment the seat is dead level and I'm finding about 1.5" inches of drop to the handlebars is about the practical limit. Lower than that and your stuff starts getting squished when on the drops. Perhaps 1" drop would be about ideal for most people. I actually prefer 2", so I'm going to try a degree or two of nose down and see how that goes. FWIW I rode a PX10 with a very old B17 as my commute bike for years with more drop than that, and it was totally comfortable. Perhaps it was because the seat was very old and saggy.
