Unlike most of the Dog Brothers, Thomas Holtmann (Gong Fu Dog) learned his weapons skills from CMA (specifically Seven Star Praying Mantis) rather than FMA.
This is the first time I've seen someone demonstrate genuine fighting skill (as opposed to performance skill) with the 3SS. Pretty cool.
He's also a BJJ black belt and his approach to grappling during stick-fighting seems to work well with his approach to the 3SS.
