Reading the “Foam” article referenced above, it says
  ‘Also never use carapils/carafoam as it is actually very foam negative.’

Huh??
I would like more information on this because it runs counter to everything else I have heard.

It’s fairly well recognized that cfoam/cpils don’t do much for foam, and only minor amounts for body.  There are better ways to improve those aspects in beer besides using grains such as these.  Even denny recognizes the lack of usefulness cpils is thought to have on foam production.

As detailed in this article (http://byo.com/stories/article/indices/35-head-retention/697-getting-good-beer-foam-techniques), if you don’t have foam problems, adding foam positive elements won’t help.  Of if you have certain foam issues (not that you do), adding foam positive elements won’t help.  I long ago concluded from my experience that wheat and carapils do nothing for foam, at least in the ways homebrewers usually think of.  I use carapils to add body if needed.

“even Denny”…heh heh…
