As many know its been preatty wet in the midwest lately. I got to the pool hall today to run my little sat tournament and I found 2 tables that had developed ripples in the felt along the side rail cushions. I figured it was a humidity issue but I also wonder if the tables werent set up right to begin with. They are valley bar tables. They have championship cloth, with 1 year old rails. When they were initially recovered, they all played like pinball machines(they still do for the most part). The rails are either too tight, or the wrong ones. On 2 tables when lagging, the cue ball becomes airborn when it hits one of the bottom rails. I know everybody sings the praised of simonis, but for a bar table, with the heavy cueballs, and amount of play is there a best choice for cloth? Also how do I determine if the rails are either the wrong kind or too tight?
