Unlike 2024, Knight's Choice did not progress to the Bendigo Cup this year, but was an unlucky third in the Group 2 Herbert Power Stakes (2400m) the start prior, which backs up Laxon's belief he is going better than two years ago.
"I really do think he's going better than he's ever been going," Laxon said.
"He's matured, he's stronger, he's got that smirk about him that he thinks he's really good, so with luck in the running he'll be there at the end."
Knight's Choice, who will be reunited with Cup-winning rider Robbie Dolan on Tuesday, drew well in barrier two, which Laxon was eager to see given he has 5kg more than he carried to victory, but she said the weather was the most decisive factor in his chances.
The seven-year-old son of Extreme Choice needs Good tracks to show his best.
"It all depends on whether it rains or not before Tuesday, because he's an absolute duffer on wet tracks," Laxon said.
"An inside barrier makes it easier. He can just jump out and smoke his pipe and conserve all his energy until the end and hope for a run through.
"Obviously he carries a lot more weight this time, but he's as well as he's ever been."
No rain is expected in Melbourne on Sunday, but anywhere between 4-20mm is on the forecast for Monday with a chance of showers on race day.
