Which are you guys choosing for August/Sept hunts, or has anyone tried both? I've been running a Mountain Star for a while now and trying to lighten up my early season setup. Application is for cramming everything back into my bag each morning. If im spiking out, I'll most likely still bring the MS. One is much lighter, but the other is much roomier. Going to a 30° bag from a 15° and switching to the uberlite over the xlite. Thanks all!
