Gnu, The game that is growing fastest worldwide is rugby seven-a-side, usually called 'Rugby Sevens.' Part of the reason for the growth is that it is a faster, more running game, without the same requirement for a forward-line of big guys. Well, fewer of them, anyway, and less big guys to get past to score, so that nations where the men are of generally smaller stature can be competitive. The main competitors are the usual culprits, GB, Ireland, Oz, NZ, SA, but it was noted in commentary that it was getting much harder to beat the 'minnows,' so although NZ are current champions at that too, it may be that their tenure is ending. Googling the NZ site for Sevens shows that current ABs are also Sevens men. The lighter ones.

I understand that both men's and women's Sevens are to be included at the next Olympics. A chance for some tough chicks to get a gold medal, eh? The USA are already on the way to that.
