We've got the "Spark" pictured to the left which is simular to the XTC and a sports climbing line called "nrg".
It just so happens we make them as well so it is really interesting reading the feedback from you guys on what makes a good line and what doesn't. I might have to start a thread
Steve is climbing on them now so i am looking forward to his review.

I still think it may be a toy motor:001_smile:

Ive got the gecko also. Thought it was a good rope when i got it, then i bought the xtc and now dont use the gecko.
What the main difference?

Just had a look on the web site, What is the difference between "gecko" and Salamander?.
The specs all look the same and with an elongation of 3.3% it doesn't seam over elastic.
Arbormaster quote between 2.5% and 5.7% elongation so you would think Salamander would be less "bungee" than Arbor Master?
-
Its Marlow that make the Salamander isn't it?

Could be a Japper like a Toyota?

16mm is pretty standard, make sure you use a good quality. I would recomend a braided rope over a 3 strand, a good 50/50 double braid will give you both long life and strength due to 50% of the material being in the cover. As steve says Double Esterlon is a good option, a Polyester like Donaghys Rhino is a good cheaper option.

That a nice looking rope you have there Drew
I have some data on the effect that Knots and Splices have on ropes that you may find interesting.
This information was published by the Department of Scientific and Industrial Research.
Reduction of strength caused by knots and splices on synthetic ropes.
Ropes made from Nylon
Reef Knot - Ave 55.6% loss of strength
Sheet Bend - 47.8%
Bowline - 31.8%
Splice - 10.9%
Ropes made from Polyester
Reef Knot - Ave 47.3% loss of strength
Sheet Bend - 47.5%
Bowline - 32.0%
Splice - 13.9%
These were results from standard ropes. With the more modern core dependant type ropes i.e. kermantle and the cover dependant 16 plait ropes greater retention of strength can be obtained as drew has found.
Common sense is required with any splice or knot. Constant inspections should be made on all ropes and if they show signs of damage they should be retired imediately.
Replacing your rope is cheaper than loosing your life!
Happy Climbing..................................................

Hey Guys,
Great to keep up to date with whats going on in the UK and with the latest gear and gadgets available.
Big Hello from NZ:001_tongue:

If you are into knots there are several great websites you can look at.
For great animated knots have a look at the Donaghys web site.

Enter Knot tying instructions and have fun.
What makes a good climbing rope?
in Rigging and roping

One this I have learnt very quickly is not all ropes are created equal.....
The other is not all Arabists like the same type of rope....
There are good ropes and there are bad ones, some climbers prefer low stretch static ropes while others prefer ropes that are classified as semi static which allows a freer movement in the tree.
There are nubby ropes like XTC and Spark then there are sports type ropes like Blaze and NEG specifically developed to work better with micro pulleys or ascenders
There are pros and cons for both types
What rope work best for you and why???
