Maloney has always rated Nature Strip as a quality racehorse because of his galloping action and attitude.
But he says he the boom sprinter will be vulnerable on the tight Moonee Valley circuit even though he scored a 5-1/2 length win at the track at his third race start.
He says Houtzen will give her all and if she is ahead of Nature Strip she will be hard to run down.
“The best thing with her is she's won at the track, she gets around the track and she's very easy to ride,” Maloney said.
“Nature Strip, when I won on him there, he didn't get around the corner too well where she can rail like a greyhound.
“You can also use her in the first furlong and she'll come back underneath you whereas (Nature Strip), you can't give him a dig, otherwise he'll over-race.
“If she can get a break on him, get an easy enough lead and put some pressure on around the corner, he might be the one under pressure and you never know what may happen.”
He partnered Houtzen in a recent Gold Coast barrier trial and travelled to Melbourne to put the filly through her paces in a jump-out at Caulfield last week.
“She trialled well at the Gold Coast and the beauty with her is she puts 110 per cent into everything she does,” Maloney said.
