Lirios Armor hitch cord - first impressions

Picked up a couple of metres of Lirios Armor hitch cord at the APF on the recommendation of Honey Brothers, at 3 times the price of the Sirius I normally use I was initially doubtful and it was going to have to seriously impress me

Only used it on 2 climbs so far, one large (SRT) and one smallish (Double rope) and I have to say I was very impressed, used it with my usual knot - distel. Its very smooth, holds well and tends nicer than any cord I've used before. So if it lasts I may well be a convert! I won't speak to soon though, its early days yet, more later...

Working a Spar SRT

I dismantled a large oak earlier this week, the crown came out easily enough and we were down to the stem by lunch time(ish)

Call me a cheat for using ladders but It's still the quickest way into a crown!

The stem was obviously slightly more time consuming, especially as it was up to a metre in diameter in places and due to a fragile patio underneath everything had to be lowered. Now I quite enjoy blocking down big lumps of wood but they can be pretty time consuming to set up, which is why I frequently work them SRT.

I simply choke my line at the top of the last cut, descend to where I want to cut next (with rope wrench attached) I have the pulley block, dead eye and rigging line clipped into my anchor ring, so they are out of the way and not hanging off my hips, I am then easily able to make the face cut without any danger of cutting anything. 

The stem after 3 or 4 large lumps had been rigged down, you can see the largest still at the base of the tree, to big to be moved we had to cut it up where it sat.

Once I've made the face cut, the pulley is attached as close to the face cut as is practical. The rigging line and pull line (if applicable) are next to be attached before I strop in, move my SRT anchor to just above the pulley, make my cut and hold on! Then its a case of un-tieing the dead eye, clipping it to my anchor ring (pulley/rigging line still in place) descend and get ready to start all over again!

When it comes to either descending to a point where I can't reach my anchor to retie it (or coming down at the end of the day) its a good idea to make the anchor retrievable, in which case I use an Alpine Butterfly. 

First enough rope is pulled round the stem to reach the next point/ground, then I tie the alpine butterfly into this long end, then simply clip a karabina through the loop and onto the other part of the rope (closest to harness/hitch) making sure the gate is facing up, this is then synched up tight to the stem.

Now I wouldn't recommend this as a permanent anchor to work an entire tree, but for working on a large diameter spar like this I think its fine; its always in sight so you can see its not cross loaded or coming undone, and the stem is large enough that the krab is being weighted along its correct axis.  

Coming down at the end of the first day

Retrieving the anchor 

Then when it comes to retrieving the anchor you just pull down on the knot side of the rope until it gets to you, unclip, untie the butterfly and pull the rope down. 

Token TIP (tie in point)

I've been doing quite a lot of storm damage work lately. Any of you with experience of this will know that its not as clear cut as most stuff and you can't always rely on having a suitable anchor point to work from. So you frequently have to improvise, compromise and generally make do.

Take this willow from last week, it had lost its top leaving only a couple of biggish side branches that curled upwards, over a fence, so couldn't be dropped in one. Not practical to get a cherry picker in for it so had to be climbed.

I'm probably a good 1.5m above my anchor here, with enough rope in the system that I would probably deck out if I swung towards the tree, but by keeping my work positioning strop attached to the branch I'm walking out on I'm protected from a major swing and it at least offers a small amount of security should the branch fail. 

By working single line it meant I could tie in around the broken stem and maintain constant friction on my hitch. Now some may say whats the point in this TIP (tie in point) when you'd hit the deck if anything were to fail, the point is that any roping point is better than none and this one gave me something to lean against when walking out on the branch, and by balancing the tension between that and my work positioning strop I could stand upright comfortably and securely, enabling me to safely remove the branch in manageable sections. 

My Rope wrench/SRT set up

I did a post last week on some of the benefits of SRT and i thought I'd just share a few pics of my current rope wrench set up

I love climbing single line, but I don't use it for every tree, so having the wrench set on a Dmm oval, means that I can quickly switch from double rope (DRT) to single. The knot is a distil tied on 10mm line, but with fisherman's either end instead of spliced eyes. This enables me to keep it real short and minimise sit back. The knot works equally well for DRT

The tether is based around a short Wild Country quick draw sling, this fits snugly in the wrench, keeping that end fairly rigid, the other end has a petzl quickdraw rubber and another karabiner rubber that stops the tether moving too much on the Krab. it is all then stiffened up with a few layers of heat shrink. 

My climbing line is Yale lime light (11.7mm) works really well with the wrench, can be a little bit bouncy when working single line but otherwise a really nice rope. May well do a full write up on it at some point.
