From my JMT experience this year, I (obviously) used the Caldera, but went with esbit and a GramCracker. Found it to be more efficient, lighter, and less-spill-prone than alcohol. Worked like a champ.
The main thing I wanted to chime in with was my observation on VVR (Vermilion Valley). With Edison Lake being lower the past 2 years, it is probably 1/2 to 1 mile further down the lake to catch the ferry.....and a bit of a drive in a van over the dry lake bed to the resort. HOWEVER, you don't have to retrace your steps. You can catch the Bear Ridge Trail on the south side of the lake and tag back up with the JMT a bit further down the trail. This modification to the trip results in minimal additional trail time.
The other consideration with VVR is, that unlike MTR, you can do laundry, take a shower, have a cooked meal, have a beer, etc. About that point in the trail, a shower and clean clothes were welcome. Feel free to bash me for enjoying a day of creature comfort....but god help me I did.... and I will probably keep VVR on my itinerary the next time I go.
