I'm thinking more about luggage, and the convenience vs. stability question, and thinking maybe it has become a moot point as I reduce the amount of crap I carry. I realized that I really don't access my luggage regularly anymore, except to add/remove layers throughout the day. That part is kind of a pain with the soft rack and dry bags approach, which means I'm less likely to stop when I should to adjust my layering. Anyone have any easy, fast, secure solutions for this? I can just use kayak or voile straps to lash my rain shell and heated gear to the rear rack, but I'm always worried they'll snag a branch on a tighter trail or get blown off at freeway speeds.
