 In any case, I've found the addition of 0/0 turn to the Fig-0 (what I am calling the Fig-0-0/0) to be less jammable than the Fig-0. I think Fig-0-0/0 loop is as easy to tie (though retracing the bend quickly takes a little practice), and it seems more secure and stronger with the extra support. I'm interested in views on these matters.
