Thanks for the lead on the forearm brace.
I have a 6-7 lb camera (Sony EX1) and am wondering what happens if I go with the Glidecam 2000. I prefer the shorter retracted column length as that 6" difference is significant when following babies and martial arts ground fighting. The Glidecam2000 retracts to 14.5" while the 4000 can only retract to 20". Will I only need to add some more of those washers for a GlideCam2000 to accomodate a camera that is heavier than specification?

Due to the physics of how torque works (force Y applied at distance X from center of gravity...... in otherwords multiple the weight you are using by the distance from the center of gravity which should be just below the gimble) you may end up needing to apply a LOT of weight at the shorter distance of the 2000 in order to make up the same torque needed to balance the heavier camera using the longer base of the 4000. What that means is it may be shorter to use the 2000 but you may need to add a pound or more of weight to equal the additional camera weight. And that extra weight all focused on the handle (unless you are using the smooth shooter spring arm & vest) will make the usability of the unit suffer significantly.
As for very low angle shooting to capture good footage for ground fighting, consider a quick upside down flip of the camera. If you have an external LCD and a flip mechanism, then you can flip the glidecam and capture decent footage while shooting upside down. Then in post you can just flip the footage back again to compensate.
If you cannot have any pauses or obvious jarring changes in the footage like that. then have a stationary camera on wide angle to cover for the momentary flip transition.
