late to the thread, but i might suggest that something equally important is your cooking gear. I presume that you've got a bunch of it from horsepacking, but if it's weightier, you might consider a set of GSI Bugaboo Camper, or Pinnacle Backpacker sets. These pots are extremely temperature efficient. Mine get hot by running them under hot water in the sink. They're also non-stick and clean up quite well.

I would fashion a cozy for them as they will also cool off quite quickly once removed from the heat.

As for stoves, I gave up my Whisperlite as being too heavy, cumbersome, large, and frankly dangerous in favor of my old and trusty CampingGAZ Bluet. Going to have to give that up for a Primus or Giga as it's getting harder and harder to find fuel for the Bluet.
