The first thing I ALWAYS look for over everything regarding ground work and self defense is weapon/hand control. "Position over Submission" still holds true but being weapon centric and looking for limb control is key. In most of my fights that have gone to the ground I have used my Guard to neutralize the weapon yielding limb. Be it knife or stick, the weapon is always #1 for me. I really like Crafty's block of material for Guard. I can't wait to see this stuff in the Kali Tudo ground DVD.
Woof!
