big fan of wool in the wet. how much, how long, depends on temps.
the rain jacket (showers pass at the moment, but also an old marmot precip that is pretty much done) would come out for snow, freezing rain, high wind, camp, or long descending.
i also have a pair of rainlegs, those work for my rando riding in spring and late fall. too warm on the legs for summer.

i've thought about getting a poncho / tarp combo for camp. still might do it. love my carradice poncho for town riding (when i have fenders). too heavy to take on a tour.
a sil version would be good for camp, not for riding, as it would be too light in the wind.
