Searching for a surf documentary, which one is it??

Hello!
One of the best documentaries I've ever seen is a giant wave documentary.
I saw this many years ago and it is really amazing, but I can't remember it's name.
I recently watched Riding Giants
http://www.imdb.com/title/tt0389326/
which I think may be a version of the documentary I watched many years ago. The documentary film Riding Giants was also awesome but I can't help but miss some scenes in the documentary I am searching.
I think it was Laird who in this documentary, I don't know the name of, was talking about
running on the sea floor with a stone to train also I remeber them specifically talking about
diving through caves to train the mind for the times when getting pulled down by giant waves
I even remember seing scenes of this diving in this documentary.
I really do believe these scenes added so much more to this amazing documentary than Riding Giants, which was also superb btw especially in 1080p and perfect sound with all the IMAX scenes in it in the end.
Anyways I would really really appreciate if anyone knew exactely which documentary I am talking about and could give me the name of it!
Happy surfing surfers, seems like a fun activity indeed!
