Joomduck's Profile Pro is an excellent addition to our site.
The client was really happy with the multiple page profiles, tabs and HTML abilities that this $30.00 component makes possible.

We did encounter a problem in a conflict with CB's Coolness template. Here's the note I received from JoomDuck after they solved the problem for me.

"Finally we've found out that it was related to your coolness template and CB Profile Pro javascript code conflict (on other templates the page appeared correctly).
You coolness template has a <div> element with id="content" attribute, while CB Profile Pro has a textarea with the same id that renders with WYSIWYG editor. So this <div> element was processed as textarea and thus caused the page to break. We've modified a little your template files, i.e. changed the id value from "content" to "pagecontent" and now profile type edit page appears correctly."

Perhaps knowing this will help the next pilgrim,
