...Moreover, I had good conversations in Hartford with serious, careful Petzl guys who assured me it wasn't an issue: 1)the connection is stronger than it seems and 2)the bending moment is only as much as can be induced by a line under tension (a lot less than if the ZZ were attached to a ridge surface)....
Thanks, this made today's climb a little less concerning.
After the MagThrowBag had done it's job...time to try out the zigzag...

Zigzag doing what it does...

WOW...this thing takes a light touch. Me likey.
An hour of practice with the magthrowbag a few days ago and flaking the throw line into the bag I carry a 17' lanyard in really paid off today.
