It's been discussed at length on this site. Do a search, you'll find lots of info on being light. Check out other peoples gear lists. I lightened my load by at least 100 lbs. (I went from a load in a pickup truck to putting everything on my back). After ditching the multifuel stove for a DIY alcy stove I was on my way to being lighter. You don't have to spend a ton of money on gear. When you go lighter, you are happier at the end of the day.
