I don't have a problem with someone extolling the virtues of something new they have come up with.  For Oak I would think it would work quite well but I would be rather skeptical on how how it against elm or Sweetgum.  I did watch the videos and it looks like ash or poplar.  I wouldn't mind being proven wrong on something like that.
