Possibly the worst rope I ever used.

Worse than early Marlow?

Well put it this way, I once saw a climber get stuck up a tree because the rope had hockled up so badly beneath his friction hitch. Poor sod had bought a whole reel of it as well. *cough Martin Bowers cough* ?

At least the marlow was only bouncy

Cost has a lot to do with production volume, or whatever you want to call it. Rope access workers will go through a lot more rope than arbs, say 2-3 years for an arb rope, a couple of dirty jobs or even just the one job with rope access work therefore more demand higher production runs and cheaper costs. Then there is the splicing that a lot of arb ropes have £20-£25 for a splice which easily ramps up the cost. So less people in the arb industry replacing their ropes less frequently drives up the price. At £130 for a decent rope that can last three years really isnt that bad TBH. Apparently coloured rope does cost more than you think which again bumps up the price as most arbs prefer coloured rope as its more visible in the environment they work in. 

 

Another thing I forgot to mention is a lot of rope access rope comes on 50,100,200M reels, arb rope cut and bagged and tagged into 35 or 45M lengths which costs more to do. 

 

Although you can use rope access rope for tree work it isnt the nicest to use with friction hitches or arb mechanical devices.

 

I used nylon three strand when I started 25 years ago, very cheap and very horrible compared to today's ropes.

Ironically a lot of these "working at height" type jobs would probably be better suited to dynamic rope. Those at risk of falling have to use a fall arrest/shock absorbing device , where with a dynamic rope they wouldnt need to.

Using the stretch in a climbing line to limit forces only works if you have a lot of rope in the system, something like a snake anchor limits the force regardless of rope length or type.

 

Have you ever tried trying to hold a work position on a long stretchy line ? ?

Indeed.

Using a dynamic rope for tree work or rope access would be very tiresome to say the least!

Static and dynamic when needed.
