It's interesting, I was just talking about rigging excesses with my girlfriend right before I got on here to check up on the latest posts. What we were talking about is how new books and other publications now seem to push more and more gadgets for rigging. Just take a look at any rigging info books from the last few years. Check out illustrations in the same. Everything is geared (pun?) towards using this widget or that widget to rig heavier and heavier loads. It would appear that equipment companies are now regularly in bed with the writers of these books. As it was so rightly stated here, trees are not rated. Keep in mind, one of the guys who literally wrote the book on rigging, Donzelli in "The Art and Science of Practical Rigging," was killed right before the tape that went along with the text was made, as I think I remember reading in here, by having a tree section beneath him fail when it was shock loaded by the section above it he had just cut. He was tied in to that lower section and went to ground with both sections. This fellow was super bright, and knew so much about every type of rigging gear and set-up around at the time, but he failed to give the cut section its due before he rigged it to the section below (which he also misjudged), and it was a fatal mistake. I have to admit that I prefer to cut 'em and drop 'em, but I also know that homeowners don't like to see those craters in their lawns. Ultimately, a happy medium must be found. If you're needing to rig, I think cutting smaller sections is a good idea, even though it may take twice as long to get the job done. I remember reading in the above-referenced book some line like, "You could decrease the stress on your system by cutting smaller pieces although that might not be practical." I remember thinking when I read it, "Why not?" If the author had gone for that approach, he'd probably still be around today. I don't say this to put this fellow down, since I know he was amazing at what he did, but only to suggest that we all need to consider that along with the smarts we get from experience which may encourage us to rig larger and larger sections down to save time, it sometimes pays to take it easy on the load, and take your time.
