Thanks everyone!
Nero, The guards are are analogous to the positions in Western swordplay. Full moon being "first" I believe. "Prima" in Aggrippa. The purpose of the first two spheres is to allow one to parry without taking the weapon off the line of attack. Keeping the tip pointed at the opponent also disrupts his advance and sightline.
Yeah, I can see the resemblance! I think another big difference comes in the fact that many of the fencing parries are designed with only thrusts in mind. For this reason I had to expand the concepts to include the cuts you inevitably encounter in lightsaber combat, and this is a very good way to do so without sacrificing precision. Keeping the point relatively motionless is a VERY good concept, it helps a great deal in accuracy as well as response time (less distance to travel = quicker action).
