I have a 20* incubator, no overstuff, and LOVE it. Actually got a 0* Burrow recently and love that even more!
I am a cold sleeper, and tend to do a lot of 35* and lower temps at night, with a planned February trip that could easily see 0*. The 20* keeps me just warm at 30-35 with a layer of reflectix or other light pad. I am very comfy to 40* in it.
I am thinking of getting a 0* Incubator. But is that the same as a 20* Incubator with 4 oz of overstuff? or does the 0* have bigger baffles, meaning more loft? Should I get a 0* with a couple extra ounces so I will be toasty at 0*????
The extra weight of the 0* will stink when it is warmer, but then I won't have to schlep the extra insulation of the reflectix (lightweight but cumbersome).
Arghhhh!! Decisions, decisions!!
