  1. When rigging using a spider's leg (SL) is there a one rule fits all in rigging? I am told and it "mostly" works that use the rigging line to go distal and keep the spider's leg at the butt end where you're cutting. Just for note; both the rope and SL are anchor hitched to rigging crabs with slings on (knotless rigging). The theory then is that both the spiders leg & the rigging rope are taught. Now as long as the centre of gravity (COG) is in between both tie off points; preferably nearer the middle I'd hope, then all will be well; the branch will come down HORIZONTAL! What's other climbers experience of this? With the crane rigs your rigging point is easier and more central. Rigging from the tree you're working on things are a little tighter for space in the third dimension (mostly skywards). So I am saying keep your distal tie off as far out as you can get (without wasting too much energy and climbing time) and your butt end close. Ensure both rigging rope and SL are tight and the COG is somewhere near the middle. If anyone disagrees please help as it's not been 100% or if there's an easier rule of thumb let me know. Some climbers think the SL and rigging end should form an equilateral triangle. Also whilst I'm asking does the law of physics demand that if you have a perfect rig on a SL with horizontal dropping of the branch is there more weight being put on the rigging point that the groundie is attached to; be that a simple wrap (or no wrap), port-a-wrap or whatever? Obviously there are two rigging points on the receiving end. I'm well aware that there are many out there who've thrown their spider's leg in the proverbial footwell BUT used well and in the right situation they're a great asset to the climber's arsenal IF s/he can use it with confidence.
