I saw some of this at the recent WMAW gathering - very good, professional presentation. The DVD is available from the Freelance Academy Press, which is producing a lot of good WMA material.
It's a very slick production. Center-grip shields have been gaining popularity in the SCA, and it would be interesting to see how these techniques would apply. I think that they should have chosen a different background, though. In this preview it is someone difficult to see the black clothing against the black curtains, and the sword disappears into the black also.
