I've seen a huge up Rick in the use of the ring sling usage fur rigging, I'm assuming not negative rigging. I have never used them but they appear to be super useful and fast to set up I'm thinking of buying this for a first one http://www.treestuff.com/store/catalog.asp?category_id=455&item=9012 Mybthoughtvwas tp be able to use it both in crotches, and what I'm wondering, can I girth hitch it to a stem /branch in horizontal or vertical application and use it that way too? And if so, what's my weight rating reduction? I'm not looking to load the crap out of it, but decent sized limbs and chunks as I work down. Again, I have no experience with these. If this one won't work other than in a crotch, what 2 or 3 ring product will? Thanks again. Love this place.
