Rope sleeve or cambium saver for rigging

I'm wondering if the bend radius to be considered is only the tighter bend radius.

The Belay Spool and AFB, in my mind, have less than favorable bend radii. Just used my BS the other day... still like it.
 
I personally have no issues with the bend radius on a setup like this. Can't help but feel like we overthink these things... I have used a Pinto Rig for years without issue and this is slightly bigger than that. Of course the bigger the better, but a setup like this is still nice, round, rope-friendly surfaces, and for everyday rigging with half inch rope, I myself don't worry about it....
 
I've used a ring/ring FC with half inch sixteen strand for rigging for many years. When I first started using it I did some number crunching to get an idea of loads. Given that my use of the setup was for working down brush and small limb wood I never got anywhere close to a 'compromise' rating.

I'd say just the steel ring would be really small. Not saying it's ideal, but early on I was witness to some LARGE pieces of wood dropped into a 5/8 rigged thru a steel carabiner. There are "ideal" tools for certain scenarios, but that doesn't mean other rigging hardware will sever ropes and destroy all things. It's just less cycles to failure

I’ve used sleeves for rigging quite regularly in the past. Larger rope over larger unions is best to spread the forces. Nothing is easier to set remotely.

I had an old video of spam rigging in which one side was base anchored and the moving side was through a single sleeve. The whole shabang was set from the ground and later retrieved from the ground.

You just have to be aware of what you’re asking the system to do and be realistic. Super heavy loads moving fast would best be run through traditional blocks.
 
Leather sleeve works fine when used appropriately. They make a larger version that will accommodate a larger line. Eventually you'll wear through the sleeve but they're just so easy to set up and retrieve remotely. Ring and rings are a nightmare to use around here, too many tight crotches...
 
It takes some massive rigging to burn through a leather cambium saver. richard mumford made some mod line attacheable leather sleaves. They were not good for setting remotely but they are great for setting redirects or moving rigginlines around the canopy. the velcro eventually got torn off but it was a good concept. a midline attacheable tube that was sturdy enough to remote install would be the holy grail. I dont like the house rope sleeves as much for rigging for some reason, the leather seems more appropriate but thats just a feels thing. One of the problems with the leather sleeves is that it can be hard to thread the rope. I had a fishing weight on a piece of throwline i could drop it through and pull the rope. of course that got lost. The leather tube has a bend in it that makes pushing a rope through difficult. They do make a bigger one that is advertised for rigging. I dont like that one as much because it is more likely to be difficult getting into the crotch. but it is definitly easier to push a rope through it so it gets used. Somebody told me you could powder the inside of the leather with a little talc to make it slide better. ive never tried that because i was unsure of talc on my rope. probably no big deal. I think treating the tubes with a bit of leather conditioner is a good idea.
 
I've worn through them but that was after a decade plus of use. It wore through right at the center and likely due to using it on smaller crotches. They're a consumable, it will degrade with regular use in our work environments.

The nice feature is it can be used for both climbing and rigging. I've done a lot of solo span rigging with these and they're great for removing the rigging remotely if you run the termination end up and over the crotch and base tie it down where you're working.

Installing can be a little stubborn, especially with a sliced eye, if you hold it at one end and feed a bunch in it just takes a slap across the thigh to send the bunched rope down the sleeve. Repeat a couple times and you're golden.
 
I use rrfs and all sorts of setups. However, years ago I tried a cambium saver but melted through it in no time. So I don’t use or recommend it personally.
