That integral designs parka isn't gonna be warm enough for cold ass belays. If you are a warm person, the wild things is a good bet. Patagucci's is almost the same, but more $$, and not quite as warm. I think the GoLite 6 Month Night is the warmest, lightest, and cheapest (a hundred smackers) one out there. Just as warm as my trusty Marmot Parbat Parka.
