I'm a bit late to the party but here is my $.02 worth.
With all the back packing I do in both the winter and summer, at sea level and up to 13,000 + feet I have seen my share of stove failures.
The Pocket Rockets are great but a bit difficult to tell how much fuel is left in the can. One of the hikers I go with weighs each tank before and after every trip. He then writes on it the estimated amount of fuel remaining. Not a big deal in an airplane but packing extra fuel for a week gets old very fast!
The other issue with these stoves is they tend not to work in cold temps. The butane in the can's don't flow well below freezing and may not light. If you are not going to be camping in those types of temps, not a problem.
My preference is a white gas stove. There are number of "good" ones that use pressurized fuel bottles. These work good and my wife has one BUT we never take it backpacking. The reason is my paranoia about equipment failures. On one trip to the Rockies all the stoves experience some type of failure except my Colman.
Stoves such as the Wisperlite have two problems, IMHO. First, it is very easy to leave parts behind or loose them. Second, the hose can be dropped in the dirt and get clogged. Both of those things have happened to hiking buddies of mine.
I have been using one of
these Coleman stoves for six years and it has never failed me, even at camps over 13,000 feet.
BTW,
here are some pictures of a few of the trips I have had the pleasure of taking. Hope you enjoy them.
PS. One other advantage of using a white gas stove is that you can burn 100 LL in it, in a pinch. If you know what I mean. And lets, hope none of you need to do that!
