My bad for double posting... but an interesting thing that the Treemagineers guys found with the "Worst Case Senario" rigging study was that putting a half hitch below your running bowline when rigging from above ends up putting way more stress on the tree than just a running bowline. It was all in that the slack in the half hitch added so much rope that the increase in the distance of fall greatly increase the shock load at the rigging point.
the US has no reason to do these studies to keep workers safe. We dont have socialized health care. Plain and simple thats why our safety regs arent as strict, dont wear chaps, cut yourself, then go pay for it.:roll:

When people get hurt without insurance all our medical costs go up.
Really depends where the bowline and half hitch are placed doesnt it? If the half hitch adds say an additional foot of rope and fall, couldnt the bowline / half hitch combo simpy be moved up to compensate? Anytime you increase the distance of fall loads will be greater, but to say its because of the half hitch would be false in my opinion. A more accurate statement would be -that adding a half hitch and placing it so the increase in fall is greater would put more stress / greater loads into the tree and / or rigging system. Simple physics really.
Putting the half hitch on also decreases the preasure on the final bowline knot.
Me either!
Know what I mean?
