So what is the alternative? just making shorter more dynamic linked turns?
Yes. Get aggressive, bend you knees, go on a slope that is pretty empty where you're comfortable making large turns, and start trying to do them quicker and quicker.
There's a rhythm you can get into when you can end up making really quick sharp dynamic turns. And if you're bending your knees and riding aggressively, you can control speed really well like that. When I get out on a 35-40 degree slope, rarely am I making big wide sweeping fast turns, it's short, sharp, determined turns to control speed.
