Rigging rope.

[mistahbenn]

Its something to do with the rope getting picked/snagged/ruined in a crotch. I have done it with 1/2 inch yale and it seems ok, that was until the mexican burnt it by lowering a lump too quickly haha

The friction on the branch means the core and outer can move differently. Not so much of an issue with a climbing line but the effect still happens.

A double braid is really two ropes, one inside the other. In a situation with little or no friction to the outer cover, the load is shared equally between cover and core.

 

When there is friction from rubbing on a branch the cover takes most of the load, so the rope is not as strong as it should be, and are susceptable to damage from glazing and picking.

 

Additionally, double braids are expensive ropes and ruining them by running them over crotches is a bit of a waste of money.

agreed

And Double braid rigging is not a solid rope which allows it to flatten out on on portawraps ect so aids in grip and heat dissapation

 

What kind of weight are you after.

I would either say 13mm XTC or sirius which i know treeworker sells

[kimtree]

Mostly use double estelon 9/16 and 5/8,all rigged on pulleys/blocks

 

also have smaller braided lines

 

have just aquired some 5/8 Yale polydyne

[Dilz]

how does polydyne hold up? its one that has caught my eye but have never used it myself.

14mm polydine is what I use with my GRCS. It does have a bit of stretch in it though which is good when pulling limbs away from targets.

For negative rigging its the way to go....not only do the stats speak volumes but in reality blocking down big wood even feels much less severe. A 60m length needs milking like you wouldn't believe though!

Just bought a length, can't really comment on its performance or longevity yet, but it does splice nicely.
