Are there any particular strategies or gear choices you make when going fast and light with small groups in canyons grade III and below? -- A lot of the resources I've been reading and watching indicate large packs and lots of "just in case" gear, even for moderate outings. I'm used to climbing, where a pair of two will take gear on harness plus a small pack for food, water, extras for an entire day, although moving upward acts as a strong limiting function. Assuming that your group is small and everyone is capable of moderate self rescue techniques on rappel, what would you consider "essential" gear, and are there particular strategies you use differently in these circumstances? Are there certain things that you have found particularly valuable or essential beyond the minimum requirements to navigate the particular canyon you are doing? The one good analog I have from the climbing world is headlamps - I only needed to descend by moonlight once to make that an essential, even for cragging days. My wife and I will be in Utah next month for climbing and canyons. A lot of it will just be the two of us, but will we also be joined by two others (possibly at different times) who are quite experienced in climbing and mountaineering and would be able to self rescue on rappel, barring some medical emergency. With small groups, there's going to be limited room to spread the required gear, so I only want to take what would be the reasonable minimums beyond that but don't want to leave something that could be particularly useful.
