To me it is like the progression of hiking boots. Back in the 70's boots were large and heavy but did the job of protecting feet from sharp rocks, moisture and support with heavy loads. Compare that to modern light weight boots that could provide all the same benefits but leaves me feeling more rested with a little more energy for the next days hike. I watch the weight in my touring set up, bike included so I spend less energy and recover that much sooner. A little more energy for those all day head winds doesn't hurt. So unless you plan on moving some furniture across the country, then a lighter choice should be considered for the overall enjoyment of your trip.
