Well, actually the idea is not so foolish.
I've heard from someone who made his own flightcase for his SL1200's, that he screwed the feet off, put a half tennisball in each corner of the case, and then put his TT on those tennisballs. The tennisballs act as suspension. He said that he hadn't very much vibrations anymore.
So, just hope the milk stays in the cartons then
