That's hilarious J.
KSC, I found some big scrap pieces of both 1/4 and 3/8 foam that I have used for my foot pads. The 1/4 is good to about 40 on it's own, and lower with some down socks, the 3/8 should take you to 15-20 on it's own. I'll try and box up a pad in each to send down in the next few days. At very least they would be a big boost with your therma-pad.
