It really depends on what your preference is...remember it's your game room. Personally, I don't like it as it would probably bow up in certain spots and make the shots all wrong and I'm not a big fan of the game to begin with but as I said earlier...go with what makes you happy!
AS Vili said-to hell with what everyone else thinks. If you, your family and friends enjoy the game by all means get it. It doesn't look like it would be hard to put away when not in use. Sounds like fun times with the right group of people.
