Time for a new throw line TM?
Thanks for the clarification on the name of the knot Gary I've been calling the unbraided VT a fench prussik for ages for some reason don't know why, the 6 wrap version is pretty much what I climb on all the time now, esp when on pulleys or FS.
Perhaps I'm not the only one who is confused about it?
