I've had both, I sold the UTE, but I'm a small person and it was toobig and not suspended well enough when loaded down. If you were in a cold climate and had a fat sleeping bag/ warm layers/ mountain serape etc, it's proobably pretty good.

I use the tarahumara (scrapped the HPG harness and made my own lighter straps) for my day hunts/ scouting trips, umilindi is a nice 3 day pack, but I'm in a warm climate where I can generally sleep fine in a hammock
