So a 10 ounce sherpa that fits in your pocket will make or break you or you'll have to get paid to carry it?   :'( Sure am glad I dont trip with any of you. My main use is for traveling or fishing, it is a very nice to be able to tell if a front is coming in based on barometric pressure, or if this would be a real good day to fish real hard or paddle real hard, a good night to really button down or not or sleep under the stars. For me and the limited time I have tripping in Quetico it is worth the 10 ounces I have to carry for the benefit it provides. Peace out
