Thanks for your replies; I greatly appreciate the benefit of your knowledge, experience and insights. The link to the ball roll-off tests isn't currently active, but may be restored today. The table installation was completed on 2/16/18, and the ball roll-off tests were done on 2/27/18. No levels have been used since installation, but a fitter will be back next week with a full box of equipment. The manufacturer plans to replace the Simonis 760 cloth we preferred for the Golf game we normally play, with Strachan 6811 cloth, normally used on snooker tables, to solve the ball roll-off we've observed--they've viewed the videos we made. Of course, re-leveling the table will be part of the process.
6811?....now the table is guaranteed to roll off....the bottom rail will roll in....
...the top rail will roll out....the side pockets will roll in or out depending on which end of
the table you're shooting from.
When you're spinning with or against the nap, different reactions require different aims.
I think the problem is with the table itself...and it's true that fine cloth will not mask it...
...but I suggest to resolve those problems before you re-cloth...
...and maybe put on 860.
The snooker cloth will mask some of the table problems for a while....but as the cloth
gets older, they'll show again.
They put heavy, coarse cloth on many bar boxes to disguise how bad the table is....
....but your table should be above that.
