Late last night, I got thinking about the camera's stability... and in a half-sleep mode, I thought about a skyscraper. And surprisingly, it's a good comparison.
If you take two buildings of somewhat similar height like the Empire State and the Sears Tower. The Empire State is very stable as it is covered in masonry. The Sears Tower on the other hand is very light being covered by glass and wobbles like crazy. To make it liveable, light buildings rely on a mechanical stabilizer on the top floors. Some use a pendulum attached with shock absorbers, others use an oil tank with an anti-wave system and others use a block of concrete that floats on a thin sheet of oil and is kept in place with shock absorbers.
The Titan 8x10 reminds me of light skyscrapers. Now, there are a few ways it can get stabilized. Adding weight to it would be one. But the best would be to have the camera side mounted on some type of very rigid gimbals (a bit like most field cameras). This would reduce the height by half and make it at least half as susceptible to movement.
As a last ditch effort, being able to mount some stabilizing device to the hotshoe would be the simplest thing to do.
