I just bought a 25 year old Brunswick table that was original owners and they never changed anything on table . When I went to look at it I rolled balls at different angles and up and down and it was not real lively. Got it home and I put new Simonis 860 felt and K 55 cushions now I can shot the cue ball and make it on a five cushion shot with a some power but controlled. They say most cushions start to lose bounce after 20 years
