Nice vid. The "Redondo" pattern that you see starting at 03:17 is a part of a form that I learned as "Balla Balla Redondo." This is a two-person form wherein the student practices various ways to circle around the opponent. There are four "redondos" (circles) in this form - and there is an introductory section and transitions between the circles. It's a great form because it teaches different aspects of timing, angling, and distancing within the context of a circular footwork.
Master St'James shows a variant of what I learned as the Second Circle; following is a version of the First Circle:
Following is clip of Master Panto Flores demonstrating another variation of Balla Balla Redondo; here the techniques are done on a half-circle rather than a full circle, and I suspect that what's shown is improvised to some degree.
Still the important aspects of using footwork to control angling, distancing and timing are shown to a fine degree here.
I have that on DVD, it's outstanding, some of the only Escrima that my Silat teacher can't find something wrong with. I really love the espada e daga stuff with actual metal sword & dagger. Serious skills.
