Thanks for your interesting response.
Initially we would be selling largely to the same audience but offering them something different, like Sevens in rugby union.
The point about Nines is that as a shortened form of the game, it is far more flexible in terms of expanding the audience and the geographical spread of the game.
But a lot would depend on how it was organised and whether it had a decent promotional infrastructure.
Those are not necessarily strong points for our sport.
As for taking the game to towns and cities where professional teams don't exist, we did that for a brief time in the 1990s, but it petered out through a lack of ambition.
