Familiarity: I've used it several times
I went with the 7 Pump/LW as I am a bigger guy (5'10", 195lbs) and it provides great padding and insulation for me in cold weather. I have spent the last two weeks in Yakima, WA and temps have ranged from 15 degrees up to 40 degrees and I have had plenty of insulation. This pad has been a moneymaker as I am accustomed to using my Army Issue sleep pad.
