I was refering to the sling to attach a block to the tree- sorry

So if i'm I'm using a typical 16mm double braid with a SWL of 650kg (10 to 1 FOS). What would you use as a pulley and spit tail and in what cofiguration?

 

I use 16 mm too Pete, my pulley is rated to 3000kg and it is held with a 1" dead eye, I am not sure of its swl off the top of my head, i have a flying capstan and a home made bollard, the capstan uses a 3 ton round sling and the bollard two 4 ton ratchet straps The weakest part of my system is the slings which i use for all branch lowering and smaller stuff these are 300kg swl. https://www.gustharts.com/Products/Arborist%20Equipment/Arborist%20Climbing%20Equipment/Strops%20%26%20Lanyards/ Bottom right, come in different lengths, only a couple of quid.

 

I also use a couple of home made spiders made from 13 mm climbing line.
