One horse is unbeaten, the other is unraced but leading South Australian trainer Phillip Stokes expects both of his Moonee Valley runners to be competitive on Saturday.

Lucky Symbol has strung together three wins from as many races at Morphettville and puts his perfect record on the line when he carries 60kg topweight in the Top Cut Handicap (1200m).

"He's up in weight but he's adaptable and can come from behind or in front," said Stokes.

"He'll be very competitive and the tight Moonee Valley track won't be a problem."

Stokes will freshen up the gelding after Saturday and target him at the Group Two Yallambee Stakes in March.

Stokes' other runner, the two-year-old Eclair Choice, had trialled well against other his own age and he expects him to hold his own in his first outing in the Quest Moonee Valley Plate (1000m) where Mark Kavanagh's Chivalry is the short-priced favourite.

"He's shown plenty at home and we've got a few two-year-olds we can line up against him," said Stokes.

"It's a bit of a lottery with first starters but I'm happy with my horse and he'll be competitive."

Both horses will be ridden by Dom Tourneur and they rate as Stokes' best chance for Melbourne success since Eclair Big Bang's spring campaign.

Stokes has welcomed Caulfield Guineas Prelude winner Eclair Big Bang after an eight-week break.

He will prepare the three-year-old for a shot at the Group One Goodwood Hcp in May, South Australia's richest sprint race.

Stokes has reassessed Eclair Big Bang's program and will opt for shorter distances next campaign.

"We'll probably keep him for sprinting and run in the Goodwood and maybe go up to Queensland for their winter carnival," he said.

After winning the Guineas Prelude over 1400m, the Savabeel gelding flopped in the Caulfield Guineas (1600m) finishing last of 14 runners.

"I think if I had trained him differently and kept him for sprinting I would have had a better result," said Stokes.

"But after you win the Guineas Prelude it's hard not to have a go at the Guineas."
