I just found some very interesting clips you might want to see:
Although it's amateur footage, it's still good enough to make the case for a brushless gimbal on a Steadycam-like stabilizer. Considering how well it cleans up his bad Steadycam work, I'd say it's a winning combination.
Imagine what it could do for somebody who knows what they're doing.
If anybody wants to try this, I recommend puting a brushless gimbal on a Steadycam rig, shoot some footage, and post it on Youtube. I suspect it'll be particularly useful for long lense shots.
