I'm pretty sure he said "I think they should do this...". I'm pretty sure that such opinions when discussing sports like freeskiing or snowboarding are worthless - they completely miss the point that people can and will do whatever the fuck they want. He also used the example that people mastered dubs before trying triples - that's just not true. When people started trying triples the exact same thing was said ie "this is stupid, they haven't even done all dub variations yet". The same was said when people started doing dubs ie "they should do all different off-axis spins before doing dubs".
Such precribed approaches have no place in the sport in my opinion. Fuck taking evertything one day at a time - there will always be people who will concentrate on style and will have fun putting innovative tweaks on established tricks, and there will always be some people who will try and do more technical tricks that have have never been done before. Both of these approaches and everything that happens in between is what progresses the sport and prevents it stagnating into the regimented FIS type approach that freeskiing and snowboarding originally tried to get away from. It's not a choice - people can be throwing triples whilst others do new things with dubs whilst others do mind blowing stuff with 180s (eg Delorme shuffles). Isn't that why we enjoy it so much, becuase it's impossible to second guess all the different crazy things people will be doing next?
Just my two cents.
