The Gore Guineas proved to be a forgettable run for the daughter of Captain Rio in the hands of jockey Lee Callaway after getting caught in an early speed duel, but she bounced back to run a bold second behind Another Coup in the Dunedin Guineas.
Madam Bentley gives the husband-and-wife team two chances in the 1400m feature, and Parsons believes the distance is ideal for the winner of three races.
She's always looked like she would be better, and she has been better, at 1400m - her maiden win was over 1400m.
"John said he had been a bit easy on her since Riccarton.
"She's not a bad filly when everything goes her way so hopefully she can put her best foot forward today].
"But you would have to lean towards the other filly."
Final Shinko makes his juvenile debut over 1100m but Parsons said his best would be on display in several months. "He's a nice horse and does everything right. Chris Johnson likes him but he'll be better as a 3-year-old. Whatever he does [today], he'll be better with time."
Parsons rates Locket in the open 1600m as the best of the team's other seven runners, despite a flat seventh at Riccarton on February 20.
"Don't ask me to explain Riccarton - the only thing is I had got kicked and I hadn't been riding her in work myself.
"But when I did get on her, she's still working beautifully, so we're at a loss to explain Riccarton.
"In saying that, last year she did the same thing when she had enough. But her work through the week was very good."
