Steve, the key to Billiards cloth is to stretch it tight, but not so tight as to not be able to install it...LOL Heated slates also help with the speed of the tables as well, but so do the cushions, and how tight the cloth is wraped around the cushions. Wetting the cloth only makes it stretch more, but that causes the cloth to loose it's spring, meaning it will lay on the slate lifeless and come loose much easier later on.
