I vote for diamonds (9 ft of course).
The only way I see diamonds turning off customers, is if you have a few decent players
who are easily fazed by the tight pockets, or brunswick fanatics who flat out hate diamond rails,
or tournament blue cloth, or whatever.
In my experience there aren't that many people in either group.
Bangers and most intermediates won't know or care.
At the same time, you will draw a few extra serious players who like diamonds specifically because
it's what they see the pros play on in events like the US Open, Mosconi Cup, and TAR matches.
I've known players who go out of their way to go to a room with diamonds even if other rooms are closer.
Those serious players may insist on diamonds when they gamble, and if they bring action,
you draw people who want to sweat the matches.
