The HSBC Sevens World Series, which starts tomorrow, is packed with eye-catching players. Paul Radley picks seven of the best to keep an eye out for. <b>Emosi Vucago (Fiji)</b> - The half-back is livelier than a wasp with attention deficit hyperactivity disorder. The flying Fijians have lost key personnel because of injuries in Australia, but Vucago will still give them wings. <b>Frank Halai (New Zealand)</b> - With DJ Forbes setting up the play, and the great Tomasi Cama providing the ammunition, Halai, the burly Kiwi wing, should be able to pass himself off as the latest "new Lomu" again this weekend. <b>Renfred Dazel (South Africa)</b> - While the injured world player of the year, Cecil Afrika, may be as good as irreplaceable, the South Africans know they still have significant firepower in the form of the pocket-rocket Dazel. <b>Mat Turner (England)</b> - One of the survivors of England's trophy-winning campaign in Dubai last year. The South Africa-born flyer has greater responsibility now Ben Gollings has gone, and he scored five tries last weekend. <b>Paul Perez (Samoa)</b> - The Samoans are having to rebuild after the gradual erosion of their series winning side from two seasons ago. Mikaele Pesamino and Alafoti Fa'osiliva have moved on, but Perez is carrying the fight. <b>Tom Habberfield (Wales)</b> - The Welsh XVs team put an accent on youth at the World Cup, and it suited them. Paul Jones, the sevens coach, has always backed youngsters, and he has a new gem in this 19-year-old Osprey player. <b>Marcelo Montero (Argentina) </b> - "I think he is the next star of Argentina." So said Nicholas Fernandez Lobbe, their sevens coach, after Montero, who turned 20 last weekend, scored seven tries in the opening leg of the series.
