Using catamaran-style Goode skis on water allowed me to do as many triples as I wanted (without stopping due to pain in my back, heals or ankles) for the first time in over four years because the force of impact is reduced with less surface area entering the water.

I also had the pleasure of using their extremely light weight snow aerial skis for my final season on the World Cup Tour and they served me well in the 2006 Olympics.

They are much lighter than any other skis out there. I can make bigger adjustments to the rate of rotation (flip) with my arms because, with lighter feet, my arms weigh more compared to what they would with heavier feet. That means, for example, if I put my arms down to speed up the flip by bringing more weight towards the center of mass, the flip speeds up more than it would if I had more weight on my feet.

The same is true for stretching to slow down the flip. Imagine that I had 50 pounds strapped to my feet and was flipping faster than I wanted to. I’d move my arms up above my head (away from center of mass) to slow down the flip but they wouldn’t have much of an effect. If, on the other hand, I had zero pounds on my feet, lifting my arms would have a big effect on the rate of rotation. Therefore, Goode skis give me more control and more room to adjust for errors made on takeoff when rotation is set.

The same principles apply to twisting but the affects are even greater because rate of rotation is controlled by two things; either moving my feet or my arms but twisting is controlled almost entirely with my arms. The affects of arm movements to create, speed up, slow down and stop twist are greater when the mass being affected, my body, is lighter.

In addition, once the twist is generated, centrifugal forces try to pull my feet apart. If they come apart, that slows the twist down but with lighter skis, it’s much easier to hold my feet together to keep twisting fast.
