Ryan the not as old as that other Ryan--- some interesting variations. You will go far.
About that 1.2 oz. stove of Bill's. I believe that the inventer himself raised some reservations about the use of that stove on RJ's venture. I, of course, have grave doubts about using either open fires or wood stoves on this Uber-light adventure. I stated some of those objections before and won't repeat them.
I really would like to see a cooking system that more people are likely to employ ( at least out here on the Left Coast) and would be legal to use in Alpine areas in the National Parks I frequent ( such as Yosemite, King's and Sequoia). Also, a stove that can be used in enclosed (but vented) spaces like tents or vestibules or snow caves. I wouldn't use the Billstove (TM) in such places. In Winter, I find I sometimes must use a stove in those very places.
You and Bill should and ought to test this wood stove in Winter conditions and see how well it performs in melting 2-3 liters, using peices of wood that reflect real world conditions ( different species, fine and loose grained, hardwoods or conifer, wet or dry. It would be very interesting. Perhaps some of my concerns could even be rebutted.
The choice of headlamp-- If we went for a sub 1 watt led headlamp ( to save weight and have extended running times) I would opt for the Aurora or Tikka. They are considered much more reliable than the Energizer Essentials and much more water resistant. You might want to check out this review:
and check out the site"s other headlamp reviews. Craig of Flashlight Reviews is considered by many to be among the most reliable authorities on all things involving portable lighting.
The Cocoon Pullover/ Nunatak Balaclava option you put on your list is definately one to consider. If it wasn't for the intregal hood on the Belay Jacket and the eVENT outer ( which makes it a more versatile insulated jacket for the purpose) and the fact that it's inclusion on the trip will probably make us all want to buy one (is this a plus or a minus?)-- I would favor your suggestion. Sorry for the run-on sentence. Interesting what other people might favor.
Finally Ryan, I noticed on some of your postings you have used my winking ;-)> just so you know the > represents a goatee (which I sport). So unless you have one you might want to use ;-) or even ; ) --I have a very long nose. ;-)>
