I just returned from a Gunfight Course in casa Grande, AZ. This is approximately the sixth or seventh time we have taught the Kali Fence and False Lead, and Kali/DB footwork learned from crafty in conjunction with FOF.
One of the things we constantly struggled with was that students with poorly developed footwork skills would tend to backpedal when pressured. This invariably led to falling backward and getting smoked by the attacker while they either tried to regain balance or after their head bounced from the fall.
The thing I have immediately noticed is that beginning in the False Lead/Kali Fence sets you up for angular forward movement (which has shown to be the most adventageous in the close gunfight drill). Conversely, this starting position makes it exceedingly difficult to back pedal as the feet are not positioned to facilitate this.
I am seeing normally slow students, lacking in agility, now able to get off the X to the defense angles and get shots on their attackers. It is truly a joy to see.
