I am going to install a new cloth on my table soon. I feel the table always played long since I first replaced the cushions a five years ago. I have a gold crown with super speed cushions. Is there any way to adjust the rails while I am replacing the cloth to get the table to rebound truer/shorter than it does now? I am not looking to replace cushions if I don't have to but will if that is the solution. Any ideas are appreciated, thanks.
