I went with the Rim Runner. The Mule would carry water and some small essentials, but not much else. RR carries the small essentials plus more water (I added a quart nalgene bottle), a stainless steel cup (nalgene is nested in the cup), MSR Pocket Rocket and fuel cannister, sil-nylon tarp, Thermo-Lite Bivvy, para cord. It's light and carries very easily.
