Kirk, thanks for the idea about "media codes" I had no idea, and this is sure to save me some $$ in the future. I will always search for that now..

Back to the sleeping bag subject.. I read your latest posts, and your site in more detail. You were willing to go with Marmot Pounders, a "40 degree" bag, which I happend to have researched heavily about a year ago;(read every review I could find) consensus is, it is not that warm, maybe 45' or higher. Therefore, I suggest the Lafuma synthetic "Extreme 600"(refering to it's weight of about 600g). It is a 1lb 4oz bag honestly rated via EN13537 to 45'F, for about $53, no tax if out of state, no shipping charges; great deal! ..at the same site;
That price includes Kirks GREAT tip about Media Codes.
I was really wary of down bags a couple years ago, afraid of getting them wet, so I bought Pertex shelled synthetic-fill 'Snugpaks', 700, 800, and 1400 grams. I highly recommend these bags (of course; they are what I chose), but they are expensive. But I digress from the point of my story.. I ended up discovering and buying Montbell Down Huggers, and I only use down now. Half the weight, and so comfortable! I pack them in a SealLine StormSack dry bag, which BPL rated highly, and I tested to be waterproof. But you need to trust your gear; so maybe synthetic is best for this trip.. Another good but pricey choice is a Montbell Super Stretch bag in synthetic instead of down. The stretch system is wonderful for numerous reasons.
