Rex Lipp expects a sharp improvement from Express Air but the Toowoomba trainer still has some lingering doubts about the mare's winning prospects at Eagle Farm on Saturday.

The Group Two Queensland Guineas winner will step out for the second time this campaign in the Listed Just Now Handicap (1300m) with the in-form Stathi Katsidis again in the saddle.

Lipp's judgment proved spot-on when he declared Express Air would be vulnerable when she resumed over 1200 metres at Eagle Farm on November 21.

The daughter of Piccolo drew in the middle of the field and raced with the backmarkers before stretching out in the home straight to finish 11th, only four lengths behind the winner Black Prince.

It was the four-year-old's first start since finishing eighth on a heavy track to Za Magic in the Listed Sunshine Coast Guineas (1600m) at Caloundra on June 27.

Lipp believes Express Air has made considerable improvement since last month's return but both he and Katsidis agree she will shine once she steps up over further ground.

Her main summer mission is the Listed Bernborough Handicap (1615m) at Doomben on Boxing Day.

Stewards reported Express Air suffered lacerations following her run behind Black Prince.

"She knocked a scab off her leg. It's nothing serious," Lipp said.

Lipp will be guided by Express Air's summer form before deciding if she's up to a trip to Sydney for the Group One Coolmore Classic (1500m) at Rosehill in March.

Express Air has competed only once at the elite level when she finished eighth to the Bart Cummings-trained Russeting in the Winter Stakes (1400m) at Eagle Farm two weeks after her Queensland Guineas triumph in June.

Meanwhile, fellow Toowoomba trainer Tony Sears is hopeful the talented Choistar can discard his wet-tracker tag when the colt launches his Magic Millions Trophy bid in Saturday's Gold Edition Plate (1200m).

Choistar will be having his first start since finishing fourth to Linky Dink in the Group One TJ Smith (1600m) at Eagle Farm in June.

"He'll probably find the 1200 metres too short but he's been in work since the start of September and he's coming along well," Sears said.

"Even though it looks too short he'll get to the line strongly if the speed is on."

Sears will give Choistar his final hit-out before the Magic Millions Trophy on January 9 in the Group Three Vo Rogue Plate (1350m) at Doomben on Boxing Day.

"The Vo Rogue Plate should top him off nicely for the Magic Millions," Sears said.

"I know his form says he likes wet tracks but I don't think he's purely a wet-tracker.

"It's just that he handles wet tracks a lot better than others."

Choistar was trained early in his career by Michael Flanigan who touted the son of Choisir as a future Derby hope following his victory on a heavy track in the Listed Fernhill Handicap at Randwick in April.

"We planned to send him to Melbourne for the Victoria Derby but he had a tough autumn and winter campaign and needed a longer spell," Sears said.
