Thanks for those last two.
I was thinking the two guys were doing a good drill then noticed they were Sifu Gary Lam's boys so not surprising. People I know who know him say he is a top fighter, used to collect cash in Hong Kong (not in criminal sense) and so really had to learn to fight. Big scar on his arm from skin graft after bonsauing a machete.
The other clip was good to. Makes me want to buy a stick, lol maybe when it gets warm again.
