I go with the Reflectix. Always carry one sit pad size for the foot box. If I think I might be pushing my UQ, I'll bring a second to kill any cold spot that might develop. Lighter, less bulky. The more you use the pad(s) the quieter they become.

I avoid using full length pads of either CCF or Reflectix, and find condensation isn't much of an issue, with just a couple small pieces.
