Jacqui Cooper and Lydia Lassila have jumped to their second quinella of the season, taking gold and silver medals at the first World Cup event to be held on the Vancouver 2010 Olympic jump site.

Cooper collected her fourth victory of the season in a weather-disrupted single jump competition, extending her lead in the World Cup title chase to 175 points over Chinese skier Nina Li, with just three events remaining.

The women’s training and competition was disrupted for more than five hours by heavy snowfalls and the familiar thick fog that had forced the cancellation of Saturday’s mogul skiing event.

When the skies cleared late in the afternoon, Cooper delivered a high class triple twisting triple somersault on the back of a handfull of training jumps, scoring 101.85 points.

Lassila was right behind her Flying Kangaroos team-mate, earning 95.17 points for her triple twisting double somersault.

Bronze went to young Chinese jumper Shaungfai Dai on 93.67 points.

Cooper now has 520 points on the World Cup standings, a healthy margin over Li on 345.

Lassila’s silver lifted her to within four points of the Chinese skier on 341 points, in third place.

“I just needed to know that I was going to be OK today,” Cooper said after claiming the 23rd victory of her career.

“Experience is massive and you don’t get to 35 without a lot of it.”

“I went through every possible jumping scenario today, expecting everything from good to bad.”

“I didn’t know if I was going to compete, I didn’t know if I was going to be doing doubles (somersaults).”

“I went on the double kicker for a while, then I ducked over to the triple, I completely missed one of my training jumps and then I did the highest DD (degree of difficulty) in the world in the competition, which shows that I’ve got great skills when I need them.”

“So I’m really proud of myself.”

Lassila was also delighted to make the podium at the future Olympic venue.

“There was a lot of waiting around and revving yourself up, and at the same time trying to stay relaxed and have a good re-focussing plan,” Lassila said about the lengthy competition day.

“And because it was Cypress, you want to really do well.”

“It was difficult, the weather was coming in and it was looking quite scary, and I wanted to stay safe and not risk another injury.”

“But then there was a break in the weather and conditions were quite good to jump.”

“So I changed my mind in the end and went with my double full-full and not just a double.”

“It’s a great site, it really is, but the weather here – we expected it, but it has really opened up our eyes today to know what we are going to be dealing with.”

“So now we know and we have to prepare for that and expect it.”

Liz Gardner finished in 21st place after performing her full-full jump well in the air, but unfortunately falling on landing.

The Australian team now travels to Inawashiro, Japan, for the seventh event of the season next weekend.
