Thanks for the tip on loosening up the hang - I haven't noticed a ridge yet, but knowing how to fix it will be huge if I do run into it. I tend to sleep pretty warm most of the time, so I am hoping with a baselayer I can push it close to 0 C, but I guess we will see how the trip goes. My plan is to try it out the first night completely stock, and then adjust as I go. I know that first night might be a bit cold, but I figure I should start simple before I add anything to the system. I will report back once the trip is over.
