A month after the curtain was drawn on Happy Trails' career, his two-year-old sibling can enhance the family's legacy on debut at Rosehill.

While trainer Gary Moore will be in Hong Kong overseeing Takedown ahead of Sunday's International Sprint at Sha Tin, he may have cause for celebration a day earlier with All Too Huiying in the two-year-old handicap in Sydney over 1100m.

The All Too Hard colt is out of Madame Flurry who is also the dam of Group Three and Provincial Championship winner Danish Twist.

All Too Huiying's most famous half-brother is popular gelding Happy Trails.

He retired after November's Emirates Stakes, his 35th Group One race, when trainer Paul Beshara called time on a remarkable career which netted three wins at the top level and more than $3.2 million prize money.

Moore is positive about All Too Huiying's chances after his barrier trial win at Warwick Farm on December 2 and third in a heat at Rosehill on November 22.

"His first trial when he ran third was full of merit but he was very green," Moore said.

"I trialled him again on Friday at Warwick Farm and I thought he showed very good ability."

"He'll go into Saturday's race with a very good chance."

Godolphin colt Coorg won All Too Huiying's first trial and is set to line up in Saturday's race alongside stablemate Lutreola who was second in the same heat.

Trainer John O'Shea will be looking for his fifth two-year-old winner for the season which would draw him level with Tony McEvoy.

Moore won't be the only Australian trainer in Hong Kong watching the race.

Gary Portelli is also in the Asian racing capital with his star sprinter Rebel Dane, who will go head-to-head with Takedown, and has Falconic in the juvenile event at Rosehill.

Magic Millions sales-topper Chauffeur is set to debut for trainer Gerald Ryan four days after the $1.6 million Snitzel colt finished second in a Rosehill barrier trial.

Chauffeur's high-profile owners include Ryan's long-time client Damion Flower who raced Snitzel, as well as John Singleton, Neil Werrett, Nick Vass and BK Racing and Breeding.
