Steve,
I've never taken the WTC but I find it be a worthwhile investment. I just hung around a lot of folks who have taken it and remember just enough from my Boy Scout and Army days to be a danger to myself. ;-) I also believe anyone who goes out in winter should take the SMI Basic Snow Skill Course or equal.
I've seen some of the snow travel course of the WTC while out and about. Because of liability concerns, this part has been watered down...no more ice axe and fangs.
