I did consider that option. It's certainly not a bad idea and I know it's common practice for a lot of folks. The CCF pads, though they are light, are a little bulkier than I want to deal with. What you're suggesting makes plenty of logical sense, but the idea of carrying two pads (even if it's occasionally) just seems, well, inefficient I guess. I totally see the hypocrisy that carrying too much pad the rest of the time is also inefficient, but for some reason that jives better with my mentality even though I realize it's less than rational.

BTW, after kicking the tires I decided that the Nemo Siren isn't all I had hoped it would be and it will be returned. Just put in an order for an EE Revelation quilt. Feeling like that's a better match for me.
