I like the concept of the X-rings, and can see them for redirects and the initial main rigging point down to a spar. But once it comes to spar work, and replacing the block, I just don't get it...mostly time wise. If you could do negative blocking on 1, or even 2, rings then I could understand. So far all the setups I have seen would either take a lot longer for re-setting before every piece (and/or setup before even starting the spar), or they are extremely bulky rope wise due to prusiking on 2 more rings.
What I would love to see is a real time video of setup in a actual work setting. Basically a x-ring version of this video. Unfortunately my video was edited, it is 2 different log pieces, but the individual setups are real time. I am not sure why I originally edited it this way (this is a clip from a longer edited video), without going through all the raw footage from that day.
I will admit that I have not tried the x-rings yet. I have been looking at them since they came out, and almost bought some several times. The main thing holding me back is the multi rings for spar work, and not mid line attachable.
Excellent thoughts ClimbHighTree ! It's almost like you are a person I set up to stimulate this conversation on topics that should be discussed. So THANKS!
I don't add prussics to another sling and negative rig any longer; not after our new sling designs that I've been using since about maybe March 2014.
I don't want to show our new sling designs until plenty are in stock and ready to go out to customers.
The new cordage is holding up the process a bit. I expected to have these new slings out a month ago.
With either 3 of the large rings (the 28x20 rings) together, OR only two of the extra large "beast" rings, you can negative rig anything that your bull rope and lowering device can handle.
IF you break a rope, it will NOT occur at those rings following that rule. Sure you can rig plenty off a single large ring or a LOT off a beast ring, but it will have a limit at some point; so I try to set the best practices high and extra safe.
The new slings are very fast to install and lighter than a block and I throw them to the ground when I'm done with them. No prussics, nothing to add, ready to rock and roll the way they come.
Great idea on showing a real time video of the sling install for negative rigging. I will do THAT ! Thanks.
It will take some experience, but you guys will see that spars shake less, tops don't bend as much, when you put friction up IN the tree. Ground-persons don't have to be so perfect at running the rope, things are smoother and mistakes by the groundperson are not magnified like when using a no friction block.
Where I used to be calling for three full wraps on the hobbs or grcs, I'm calling for only one wrap.
As far as not mid-line attachable, my general work plan is this, while wraptoring up the tree, I have my bull rope on my saddle and take several XRR slings with me. I place my redirects and thread my rigging rope through the rings on the way up.
my terminal rigging point is then threaded. As I dismantle the tree more and more, my terminal rigging point is moved lower and it's no big deal, I have the terminal rings in my hand and the end of the rope as well. It's the end of the rope...... so you stick it through the rings. As you get lower in the tree and finally get to a re-direct, you either use or remove the redirect. Again, you have the end of the rope, it's no big deal.
When I used to use blocks, I wouldn't even open the block up either, I'd just thread the tip of the line through the block.
also, on multiple spar trees, I've gotten creative with the redirects when it was that spars turn to go bye bye. let me look for pictures.
