I have used the pocket rocket in summer and winter (though never owned one), extensively used the whisperlite, and currently have been using a "pepsi can" alcohol stove for the past few years. It works perfectly to scramble some eggs or heat water, and it is so much more light and packable than all competition. The next stove I buy will be the pocket rocket, for its potential to use in a hanging system, light weight, and simplicity.
