Interesting question ...
I have a 9' Dufferin Challenger table at home covered in Simonis, work by Al the owner of Snooker Shack.
Where I play, at the Snooker Shack, they have 9' Dufferin Titan tables, also covered in Simonis, work by Al the owner.
The Challenger is a model older (and maybe better) than the Titan. They play about the same in terms of banks and pockets accepting balls.
But this is all coincidence, the Challenger came up for same when I was looking, and these older Canadian Dufferin commercial tables are popular here in Canada

And Al is a great guy and was available last time the table moved and was re-covered.
Dave <-- in Canada
