slice...
they will find exactly what they would have found if they had removed the 18-24 screws/bolts it would have taken to take the slate out without destroying a perfectly good table... oh ya, and if it's anythign like my little 6' irving kaye, like Smooooothstroke says, they will find a lot of chalk (and chalk dust and cigarette wrappers and dead bugs and...).
just dont understand the value of destroying something when they could have kept it in good condition and donated it to a worthy cause when they were done and still found out what they wanted to know...
and, hey, i have an 8' tall bandsaw in the garage, so i like slicing things, just not perfectly good pool tables...
