A thick record guaranteed there would be no warping, something I appreciate today! Comparing the two systems now, I'd say Edison was right.
Except for when the discs are 'dished', and cause problems in playback, when the reproducer tops out and starts damaging the grooves...

I was thinking along the same lines - "So they hold up to all those leaden ballads by Vernon Dalhart!" :o
