Clyde, Roger & list,

   If I remember correctly, some of the newer Kawai verticals do not have
any back posts. I've often wondered about the long-term stability issue,
also. The ones I've seen are on our lease program, so the long-term issue
wouldn't apply here. However, it would be interesting to know what
research, etc. has been done to determine the need for back posts (or not)
from the manufacturer's standpoint. Don, anything you can tell us from
Kawai? Just curious.
