Wow I just found the perfect forum to ask the question I have been trying to find the answer too. I have normally used a therm-a-rest expedition with an "R" value of 4.4 weighing in at just under 3lbs. I am getting ready to due a longer hike in March to the Smoky National Park for at least 70 miles. The weather looks like I could have anything from 30 degrees and warm to 10 degree and snowing. Since this is all shelter hiking I was looking for some opinions about what to carry.

My plan is the carry the ridge deluxe and be done with it. I have a 15degree marmot sawtooth and plan to bring my liner. The real question is "Will I suffer?"
