As for shoulder and neck position the Dog Bros use a stance similar to what I'm familiar with, I can't quite remember but I think they call it the false lead maybe? It's like a modified boxing stance, where the torso is torqued or loaded up with the left shoulder leading and the right shoulder and stick hand cocked back in a ready position. With this stance the right leg is forward but the left shoulder leads, this gives the stick fighter more hip rotation for each strike. I think i've seen Bas Rutten describe the same stance in some articles i've read. As you incorporate footwork and maintain this loaded up stance you get the triangular footwork some FMA systems are known for.
Here's a wiki link (http://en.wikipedia.org/wiki/Bolo_punch) about the Bolo Punch made famous by Cefernio Garcia. Garcia was a pro Filipino boxer and supposedly developed the punch from a bolo knife technique used to cut sugarcane. I've seen a youtube vid with old footage explaining Garcia'bolo punch but I can't find it right now.
