Tim, The older cushions don't get hard they get soft when there bad. The advice you got is only good based on the age of the table. In the eight's they started using clay fillers in the cushions and now when cushions go bad they get hard as a rock.
Thanks very much, Donny. It's a 1971 table. So in my case, hard means good. I don't know if I mentioned that it was a 1971 table in previous posts so I still appreciate Club Billiards giving me what he thought was sound advise.
