Nick , I don't trust carabiners for rigging . See way too many break . I use them for zip lines , but I have used them and sraps to multi lower limbs before . The bone feels solid , and after doing trees for so long , It's nice to have new and cool , and there's not too much of that anymore for rigging supplies . The x rings and the backbone , cmon now . Good stuff . I'm gonna place it preset in a rope bag , might even get a cobra snake flute to get it to set itself .
On another note , they always let the new people untie the limbs on the ground , that can get painful looking down , it makes you want to carry a bag of rocks when you see the dumbest person on the ground trying to untie multiple limbs . The first idiot I see undoing the bone from the lowering line ( and there will be someone) is getting a notch whipped at him from above .
