Snowboarding appears to be in serious decline (bostonglobe.com)
“I snowboarded for four seasons,” said Sanchez. “The skis then were pretty traditional, and the technology was not advancing. But the past couple of years, the new designs have made skiing much easier, especially in powder and the woods. So I went back into skiing.”
The new technology?
It’s called rocker, or reverse camber (tech details later), and it allows skiers to take advantage of another of the sport’s trends: skiers and boarders skiing the groomed trails in sometimes densely wooded glades where making quick turns in loose snow is the required art form du jour.
