I really since I already have a block and really shouldn't care , but I can't help that I'd like to know a bit more about it. I don't want to stick to what I think I know. I want to get to the nitty gritty of the differences. We know that dropping on xrings is advantageous because of the smooth consistent friction they provide.. How limiting is the lifting if much at all.. Until we reach certain mass then is it exponentially taking more force, where the block stays more consistent.. I don't know ? One thing I'll say as a climber with no bucket,crane ,lifts. I would in the past climb the anchor tree or throw line to my desired anchor point if lucky enough to gett it and if so ty on the bull rope hoist the block with rigging line into place, lock off rope with block on porty and not want or need to climb back up to retrieve that is great , except for the multiplying forces x4 on the rigging point. . The Xrings in retrievable configuration basket 3/4 inch sling is extremely strong and your eliminating unnecessary legs of line in scenarios and unnecessary force on anchor point. I'm sure most are familiar with what I'm describing . Even in lifting its less stress on anchor point with not hanging a block and that's an achievement in it self ... Just adding to the soup here and looking for reasons to lighten my rigging gear bag. If I can do the same thing and make it retrievable and not tote around the a traditional heavy tailboard block I like that , even if the block is a work of art. For the strength to wieght ratio of xrings are awesome.
you got a good grasp on things.
You won't notice too much difference on lifting with limbs and logs with rings vs blocks, until you get into really big stuff, say 2500 lbs and over. Then you really need to be using a block to help your groundperson be able to crank enough. Let me rephrase that, yes, you won't NOTICE the difference. But if you had side by side a block and grcs and rings and grcs, the block system is going to lift a good bit faster.
The rings when lifting are not a hindrance or show any negative factors until you get maybe around 3000 lbs, then they start jumping around. meaning, the rope is biting on the ring with so much force the ring tried to go with the rope, then the sling limits it and the ring jumps back to its position, making the rigging point shake. This could be dangerous in rare situation or when nearing breaking point of rope.
Also, when lowering weights WAY above the rated load, redirect rings can vibrate/bounce around. What comes to mind was lowering about a 4000 lb car and the camera at a redirect showed them being jittery.
