I don't know, but I'm not going to try carrying it!
Joey,
Great explanation. I always looked at vibration problems a little
differently. The short version (with the Mountain in mind) says, a
increase in the mass, will decrease the amplitude of the vibration. The
vibration itself is not the problem. My RecorData back has a vibrating
crystal in it, why do I put it on my camera? Because the amplitude
resulting system vibration has no apparent amplitude. In cameras the
amplitude of the resulting vibration is the damaging factor. This is
why hanging your gear bag from the tripod works.
