I currently ride the 67.25 Revo CC. I was on a revolution prior to the carbon core. I have ridden all of the skis in the lineup and this is the best way I can describe each ski.
Revocc is most stable and effortless ski for its additional width. The ski is just a little wider throughout than the 9970. So these two skis have very similar characteristics
Its width contributes to easy deep water starts and stability throughout
Skier can accelerate, decelerate, turn and accelerate almost automatically on Revocc. I enjoy the Revo CC because it has a large sweet spot and is very stable.
9970cc needs more power to ski than Revocc due to the narrow width.
If skier who wants to have direct feeling such as edging, acceleration or deceleration, 9970cc gives that feeling more than Revocc. The 9970 is based off of the tradition lines of Goode skis starting back from the 9100. These skis have been the foundation of the Goode skis lineup.
Skillful skiers tend to choose 9970 and we have seen great results with the 9970 CC for both 34 and 36 mph skiers.
And XTRcc is between Revocc and 9970cc and gives moderate control to the skier. The XTR has a wider width and a shorter body. Very stable ski known for its quick turns. This ski is based upon the previous Nano one and has been a very successful ski across the board for all levels of skiers.
All of the new carbon core skis have a narrow side wall which allow each of the skis to sit deeper in the water while maintaining the quickness cross course. With the bevels and narrow side walls all of the skies allow the skier the feeling of a better connection to the pylon.
