I'm from the West COast of Canada, and I surf in a few different locations on Vancouver island regularly. One of the guys I see out in the water commonly is a guy named Peter Devries (featured in last month's Surfer magazine). He's one of Canada's few professional surfers.
A few months ago he started an article on a website called CoastalBC, which was a basic how-to on certain intermediate to advanced tricks.
Each trick has a long write up, describing the exact body positioning and movements for certain tricks (both backside and frontside)
Just thought everyone here would find this useful and informative. Enjoy!
