there is tons of instructional info or vids on the internet. practice makes perfect . reading or watching those materials is useless if you not doing it. how many hours you go riding per season? have you ever keep practicing one single technical all day long on the same trail when you go to the mountain? are you going ski or sb no matter what condition is? i dont think there is lot of technical rider here. in the other hand, if you really are and have the passion and you know how to access this forum(how to use internet), i dont see any difficulty to get them.
