Found this site some time ago and thought it may be of use for explanations on 2 line tricks.
I don't know if this site has been placed on the forum before, but incase it hasn't here it is.
It has lots of good free tutorial downloads for a variety of tricks. Randy's explanations are easy to understand and he does the the vids at different angles and speeds and they're free.
