Like her stablemate Snitzerland, Flying Snitzel is a Group One winner-in-waiting and gets the chance for first bragging rights in Saturday's Coolmore Classic.

Gerald Ryan trained the fillies' sire Snitzel to win the 2006 Oakleigh Plate and has had more success than most with his progeny.

Snitzerland beat a quality field of sprinters in Saturday's Group Two Challenge Stakes and heads to the Galaxy while Flying Snitzel's last start produced an upset win over Coolmore rival Norzita in the Kewney Stakes at Flemington.

To be ridden by Craig Williams, Flying Snitzel will carry 52.5kg in the Coolmore (1500m) at Rosehill, a weight that has given her trainer added confidence.

"I think she's well weighted, although I think she's close enough to the Group One winners in the race," Ryan said.

"She gets two kilos off Norzita after beating her at level weights last time.

"A big filly like her won't know herself with 52-1/2 on her back."

Dual Group One winner Streama is topweight with 58kg, half a kilo more than Steps In Time who beat her in the Wiggle Quality last Saturday week.

Red Tracer also as 57.5kg with Pear Tart next on 55.5kg and Streama's Guy Walter-trained stablemate Appearance on 55kg.

Victorian Oaks winner Dear Demi joins Flight Stakes winner Norzita as the highest weighted three-year-olds on 54.5kg in the race restricted to fillies and mares.

A Group Three winner over Dear Demi as a two-year-old and fourth in Pierro's Champagne Stakes, Flying Snitzel didn't live up to expectations in the spring.

She has matured and Ryan believes she can get up to longer distances despite her sprinting sire.

"Her dam Hula Flight won a Metropolitan over 2400 metres," he said.

"She's big and strong.

"All the Snitzels are different and he didn't race past three so I don't know how far he could have gone."

And although Flying Snitzel won her debut on a slow track, she debunks the theory Snitzel's progeny handle the wet.

"I don't want it to rain for her," he said.

"She simply doesn't like it."
