I have a thermarest inflatable pad that I used before I got an UQ. It does seem to be surprisingly warm. I am pretty sure that its warmer than CCF pad. I don't use it any more. If my feet get cold, I just ball up and get my feet over my 3/4 UQ, and I put them inside the foot box of my black mamba TQ. I tend to sleep curled up anyways, so it works great for me. It helps that I am a short little chap.
