You're confusing "being a trend whore" with "adapting to the current environment"
If no one adapted, and didn't change their tricks/outerwear style, we'd all still be wearing fucking one pieces and throwing 1080 Helicopters like we were in the 1990s.
Anyone who suggests Jossi is a trendwhore, or is copying style is a fucking idiot. How is the sport supposed to progress if skiers don't take on board, and learn from, what other skiers are doing?
