I chose Wicanders brand cork after much research. It was the only cork that I found that can be put over radiant floor heaters. Really like the look and feel of the cork. Hope it holds up, think it will. My FIL has had cork flooring in his house for over 50 years and after 6 kids it is in pretty good shape.
Anxious to try out the heated floor in Santa Fe, hasn't been below 75 at night here.
Here is the thread showing some pictures of the floor:
