I recently had a friend demo a "penny stove" for me. I was so impressed with it that he gave me his for my birthday. I have since tested it once and used it on 3 separate dayhikes, but I am no longer impressed with its performance. While it is a great stove, it seems to be lacking in ways that I need on the trail.
I have used an MSR Whisperlite on 90% of my backpacking adventures. Despite the minuscule weight of the penny stove, I still feel I am leaning toward carrying my MSR.
I seems there are legions of fans for both kinds of stoves. So what I wanna know is are you a tried and true gas user or converted alcy user and why?
