There really is no other secret aside from riding switch as much as possible. I'm at the point where I can ride about as fast switch as regular on blues, almost as fast on blacks but I'm a little nervous in trees, pretty good in moguls... I ride switch ALL the time. On any given run I'll pop 180's off anything I see and roll switch to the next one then half cab back to regs. This is great practice for fs/bs 180s reg and switch as well and it made my riding 100 times more fun. Also buttering into switch is fun too. Point is ride switch as much as possible and soon enough you will be really good at it.... there is no "secret".
