I am looking at picking one up (900 Fill) and want to know how low I should be able to use it to? I will be sleeping a warm sleeping bag (usually 5-10 degrees below the forecasted minimum low). The coldest I will be camping with be 10-15 degrees in the winter. We stay inside when it gets colder here in Michigan. I am a warmer sleeper than average, but not a hot sleeper.
I want to carry the minimum and also be able to use the same quilt in the warmer months (60 degree nights). I use a WB BB 1.0 DL and a nice big tarp.
