SimmerLite Works Great
I spent 10 days in the backcountry of the Philmont Scout Ranch of NM. Nine people depended on the stove for our one hot meal a day; the MSR SimmerLite did not let me down. The stove is most certainly lightweight and easily stored in my 1 liter pot (no cover) inside my pack.
I had to get used to the lighting procedure, but it worked just fine.
