There are several different types of bridles described, diagrammed, or pictured here: http://hpac.ca/tow/HPAC_Tow_Manual.asp#3.3. We would like to have more pictures too, and would also appreciate any comments or advice you might have. How is it done where you are?
Robin Strid died because the weaklink wrapped around one leg of his spinnaker shackle. The weaklink was too strong to break. The weaklink was made of multiple loops. At least, that's the story that I heard Rohan Holtkamp, who investigated the accident, present to the team leaders at the Worlds.
The ends of the legs of the shackle were thicker than the middle. The weaklink caught up on the thicker ends of the legs after the shackle was opened by the release cable. Look at the first article linked to above to see the fat legs.
One of the legs rotates when the release is opened and the weaklink has to slide over the thicker leg. I'm communicating with Rohan to get better answers to what happened to Robin and how to avoid this in the future.

Dave Broyles (USHGA Safety and Training Committee Chairman) comments on the spinnaker shackle here.
I'll have much more on releases soon. Send me your thoughts on bridles and releases and any pictures of bridles.
