New Zealand will be going for their fifth straight World Sevens series victory this weekend, as the biggest Sevens event of them all kicks off in Hong Kong.
It will be the fifth straight title for the Kiwis in this series, and actually their seventh in a row - including the final two of last season - and each match won will build on their phenomenal sequence of 36 straight match victories.
But Hong Kong is a bit of a bogey for Gordon Tietjens and his men, with New Zealand not having triumphed there since 2001.
"There's a real hunger in the side to win here this year. We've played very well but Hong Kong is completely different because of its prestige and quite a few of the teams have strengthened, notably Fiji with William Ryder," said Tietjens to the IRB.
"Of my players, none of them have won Hong Kong so that's the real driving challenge for them. Winning Hong Kong would mean everything to us and it would just about complete the World Series defence."
As usual, it is they and Fiji who are top of the favourites list, with Fiji welcoming back William Ryder and Lepani Nabuliwaqa as playmakers for the tournament.
Second-placed South Africa have experience on their side, with an amassed 159 events in their squad of 12, but they face an awkward pool tie with Argentina.
Samoa, in England's group, will be spurred on by the extra motivation of winning on captain Uale Mai's record-breaking 51st Series event. Mai has amassed 921 points, including 94 tries, during his time in the team, making him fourth on the all-time points-scoring list.
England themselves are weaker than usual, at a venue where they won four in a row between 2002 and 2006. Much of their squad - bar record points-scorer Ben Gollings - is from the Under-20 team that recently won a Six Nations Grand Slam.
Kenya, whose achievements become ever more impressive, appear to have a favourable draw, with only Scotland likely to pose problems.
Australia, with David Campese on their coaching staff, have the usual sprinkling of hot prospects in their squad, but will face a strong Tongan side including World Cup star Nili Latu.
Often in the past brothers have played side by side on the Sevens series, most notably all time leading try scorer Santiago Gomez Cora and brother Pablo, but surely never before have there been four sets of twins competing for the same title.
David and Diogo Mateus are two of Portugal's five World Cup players competing in Hong Kong and Robert and James Lewis will also line up together for Wales.
For Japan Kenichi and Shinichi Yokoyama both make their Sevens debuts, while New Zealand's Edwin Cocker could face the prospect of playing against his twin brother John, who lines up alongside World Cup captain Nili Latu for their native Tonga.
