ABLE PRINCE The third-place getter from last year's Sprint was back on form at the recent International Sprint Trial. John Moore's sprinter can be a fiery customer, living on his nerves in the parade yard but a flying machine on the track. And he is often underrated. The sprint format has changed from a straight 1,000m to 1,200m on a turn. Able Prince should be ready and able to perform just as well on the new course. ARMADA Unbeaten in his first six starts, Armada tasted defeat for the first time over an unsuitable distance this season, but was back to form in last month's International Mile Trial. Trainer John Size is out to erase the disappointments of consecutive second placings in the race with his former champion miler Electronic Unicorn in 2001 and 2002. BULLISH LUCK An exciting late finisher, Bullish Luck has done it all, winning Group Ones from 1,600m to 2,000m in Hong Kong to establish himself among the world's elite. He also crushed a top field in Japan's Yasuda Kinen in Tokyo last June. The one thing missing from his CV is a CXHKIR win. He missed the 2004 Cup by a mere nose, but the mile will give him his chance this year. SILENT WITNESS Former world champion sprinter and dual winner of the Hong Kong Sprint in 2003 and 2004, Silent Witness has not yet fully regained form after suffering a mystery illness in October last year, although his recent performances have been encouraging. Trainer Tony Cruz is determined to get him back in winning form, and says the Hong Kong Sprint could be just the race to do it. HELLO PRETTY One of the best four-year-olds on the domestic scene last season, Hello Pretty has been leaping to new performance levels since joining trainer Tony Cruz. He excelled in the International Cup Trial last month and may well clinch the Cup if he continues along his upward spiral. VENGEANCE OF RAIN The 2005 World Series champion looks to have fully recovered from the physical problems that prevented him racing earlier this year. He was sent to his birthplace, the Cambridge Stud farm in New Zealand, to recuperate. Trainer David Ferraris and jockey Anthony Delpech are thrilled with his progress since he returned to Sha Tin. VIVA PATACA Last season's champion four-year-old took all before him when he won the Derby and the Hong Kong Champions & Chater Cup. He had no answer to Hello Pretty in the International Cup Trial, but trainer John Moore is confident the star galloper will be at his awesome best in the Cup.
