I'm surely not questioning your technique, but I would at least try it once with bottled water. I also like the advice Anthony once gave over in the Williams thread: Work the hell outta that puck Bob, I usually load mine for at least 60 - 90 seconds with a very wet brush and puck. Then try moving it to your palm and building the lather there, palm lathering gives great feedback on hard to lather soaps.
Here's another post where I compare Williams to a woman (on the other forum tho, sorry). http://badgerandblade.com/vb/showthread.php?p=2008916#post2008916
