ccf is bulkier but lighter and waterproof. UQ's comfort hard to be rivaled in my own experience. If weight's the only concern ccf is absolutely doable, if you can feel a pea under your mattress I'd go quilt or high quality pad. my .02. Also CCF gives you the option to go-to ground if you're in an area where it's a possibility you might have to.
