I have been reading the posts on dropzone.com for some time now along with the ones located at canopypiloting.com.  I first wanted to thank all of you for the great information that you have provided.  
  I have recently become interested in starting ground launching in an attempt to enhance my canopy piloting abilities.  I came across a recent post that I wanted some feed back on.

  My questions are do you think it is necessary to take a ground launching course or is it something that you can be taught by someone local.  Or is there any literature on the subject that I can read to try to educate my self.  I have seen other posts on parachute types, but I was wandering if I could get some feedback from people who have flown canopies designed for ground launching.  How much experience should you have prior to flying a GLX, or a GLS.  I appreciate all advice, thanks in advance
