I am going to pick up a static line. Right now I am considering:

My intended application will be access ascent, footlocking, SRT climbing, recreational rappelling, swings and ziplines. I would just get the 13mm 1/2" stuff but I am worried about it not running through a petzl RIG, which is only rated to 11.5mm.

Does anyone have input on using static ropes? Brands, experiences, likes/dislikes??

Does anyone have a 13mm HTP and a RIG? Test it for me?
 
I have the first 2 for a few years and I like the HTP 11 mm the best . IM gonna pick up some platium soon and see how that rocks .The HTP 11 Ive had since o7 or 08 and its still in great shape but i gave it to one of my climbers .
 
My first truly static line ( got both cougars ) which I will use for SRT is Yale 11mm Kernmaster, Luke is out of stock...but he is getting a special color scheme so I am waiting patiently......I hear this rope beats all others hands down for wrenching....
 
Links are fixed thanks. I would love to hear more about the Kernmaster too, Adrian mentioned it to me but the elongation looked higher than HTP. Anybody know first hand?
 
So to be clear, you guys are you these ropes for work positioning? Climbing and working, ascent and descent on a RopeWrench Hitch HIker?
 
No bro I dont use static ropes for work positioning,just kidding. I actually use escalator for srt work positioning some these days.But honestly I dont Work the tree that much any more using srt .I use too alot more but I just think DDrt easier for working the tree and srt for ascent.But that may be different in 6 months . I actually liked velocity with a uni in 2010 alot but it started creeping.With the rope wrench I prefer Tachyon but im sure the HTP 11 wouldnt be so bad.Now that I think about it I dont really care just as long as the rope isnt super bouncy.
 
I am using cougar blue for wrenching these days...it's pretty static works great....I would ask countryboypa ( Derrick Martin ) and Drew ( DBTtree ) about Kernmaster they are two who use it regularly...also Jay Lyke ( moosehead )....
 
Kernmaster is awesome. When I first looked it up I wondered why we all weren't using it already. I had never heard of it before but the specs looked so interesting. I ended up taking a half spool just to get someone to order some. The dynamic capabilities of this rope are amazing but it's high strength makes a climbers weight feel like a static line. When you originally tie into it it has a little set in stretch but then it is very static no bounce at least in the systems I've used mostly rope walker or tree frog type stuff. But if ever we were to significantly load it, the specs say it has more energy absorption than any other cord in the arborist market I believe. The 11 mm I have works great with the rig and all of the assorted rope grabs I've used on it. I have not had a chance to try it with a hitch, Uni, hitchhiker, or rope wrench.
 
The only possible negative I can think of for Kernmaster is that it is not spliceable according to what Jamie Goddard at Yale cordage told me. He said it was unspliceable not by hand or stitch. I know very little about splicing or stitching so I'm just relaying what I was told.
 
Hey Swing :) That was the access line I had in Tom's sycamore, you ascended on it I think. I like it a lot. It has a very tight cover so it might be picky about cordage choice when tying a hitch, like I said I haven't tried it yet. If you get some definitely let me know what you think.
 
Ive been told by a few climbers that truly static rope isnt good for working on, just ascent. Ive been told t hat if you take a fall in it it can hurt you almost as much as hitting the ground. is this true? Because I was thinking of buying a static line to wrench on.
 
I use htp 11 with both my hitch hiker and the RIG, and it works great. I don't like the bee line with the hitch hiker on it though, seems to bind up too much. I don't feel or notice any elongation.
If I'm working SRT, this is my day to day rope.

Kernmaster plain and simple Best multiple use line. Isn't as static as some so if your looking strictly ascent I'd recommend your first two options. PMI being less stretch and more rugged, HTP being slightly more flexible and brighter colors.

If your going to be using it with work positioning systems i'd look no further than kernmaster. You won't regret it because of its incredible feel and function. It can even be used as a Ddrt line. Just incredible stuff.

Yup! X2. Great line. My 11mm runs well in everything I have tried from I'D to HH. I found a hollow braid hitch cord worked better on the HH than the beeline. Minor tweak.

A mentioned above, look closely at the specs. Stretches when you need it too. Stays round. Mine is stitched spliced.

Hey Bill, if that was Kernmaster it was good footlcking rope as that is how I ascended, soft on the hands yet not much stretch and grippy... I used an icetail footlock prussic which worked great on it.....hope all is good with you bro...

Been a few threads on this topic in the past so it's worth looking them up. But... the way I'd sum it up is:

We're doing work-positioning climbing and we shouldn't be taking falls on our gear. On a DRT system (as Tom Dunlap has pointed out many times) the rope is usually semi-static but once you double it the stretch is very low, there's no arborist DRT or SRT system that you want to be taking a fall on.

We talk a lot about using the lowest possible stretch ropes for SRT work positioning systems. Reality is to get full benefit (increased horizontal crown mobility) out of these systems you're going to be doing multiple redirects and no matter how low stretch your rope is there's going to plenty of bounce from limb/branch flex. And that's a good thing most of the time, adds a margin of safety.

This is the best info I've seen on the loading that occurs when you drop weight onto a static system. They're talking about Dyneema vs. Nylon slings but it's a great tutorial on fall factor. It's pretty surprising how much load can be generated when you fall on a static system with even a small amount of slack in it:

Yo Swing, are going to be making it up this way this summer? C'mon you know you want to!!!

I use Sterling HTP for access only, it works fine. HTP is less slippery than Escalator so hitches used for back-up grab more reliably in pre climb tests. I use Tachyon for wrenching but I think Fly might be a better choice. Stay tuned, the Fly is making a comeback with sexy new colors. The Fly is also a kernmantle so it would probably be a better choice with ascenders and stuff.
