I am using my EX1 with a Glidecam 4000 and Smooth Shooter X-10 vest/arm.
Works great!
Here is a mod I made for my Glidcam 4000 so that balancing is extremely fast and positive.

Perform the gross adjustments with the Glidecam sled, then fine tune it with the micrometric stages.
You'll need 2 Manfrotto micrometric adjustment stages mounted at 90 degress from each other and a manfrotto quick release on top.
