Heavy 5/8 in bull rope sling with a thimble and big ring for real wood.
This bull rope sling is built from 5/8 in rigging rope with a thimble eye and a large ring, sized for removals where you are lowering heavy wood. The bigger ring passes a thick rope tail easily and gives a solid point for a block or lowering line.
Once the wood gets heavy, a light sling becomes the weak link. A 5/8 in bull rope sling gives you more strength and more abrasion resistance around rough bark, and the large ring lets the eye pass through cleanly so the choke sets tight on a vertical spar.
Use it to build a rigging point for a block high on the stem, or choke the piece and tie the lowering line to the ring. The thimble keeps the eye round under load, so a shackle or steel carabiner sits properly and the rope is not pinched. On a long removal, that durability means one sling can handle pick after pick without being swapped out.
Size every part of the system to the heaviest piece you plan to drop, including the block, lowering device, and rope. Compare lengths and strengths among other heavy-duty slings before you commit to one.
Before each job, run the sling through your hands looking for cut or melted strands, hardened sections, and wear at the thimble. Look over the ring for nicks and deformation. Rig only within the rated strength of every component in the system, inspect gear before each job, and make sure the crew is trained in rigging practice under ANSI Z133 and the manufacturer's instructions.

Usually. For small limbs a 1/2 in sling is lighter and easier to handle. The 5/8 in sling makes sense for removals and heavy rigging.
No. You can choke the piece or run a lowering line through a natural crotch, but a block on the sling reduces friction and wear on the tree.
