I have been climbing for some time and have tried new stuff but I always go back to the basics,bowline for my biner with a long tail for my blakes. I like it 'cause it keeps it simple. Some guys don't like trying new stuff . That is their right but at a comp this year I realized something. If any tree climber was called in to help another climber out of a tree we need to at least understand how there system works. Climb on what you like, I do. But at least learn how the other guys set up works.....not meant to be preachy, just something I was thinking.
