Marlin-

Like IC I use down bags, have for the last 25 years. As a solo paddler the advantages of down (light weight, small packed size not to mention longer life) more than make up for the danger of them getting wet. You have to have a good tent and a good packing system. Other than some occasional dampness from cold-weather condensation (easily dried via body heat from within) I've never had an issue and I paddle in some ugly weather.
