In reply to TobyA:
i measured it twice. i used a 10m rule. I measured out 20m themn tripled it.
Then I folded it in half and measured it (as it was coiling it) I also weighed it
on 2 sets of scales. it was not under tension. I could un it alonh the corridor etc
but i didn't want to mess about too much.
I weighed the labels and packaging that came with it at 109g
bear in mind this is a brand new rope and weighs (as alpkit note) 2800g.
It should weight 2460 at 41, or 2501 at 61 or even 2542 at 62
still someway off 2800. Let's say i am rubbish at measuring at it actually a whopping
65m long (giving me an extra 8.3% extra rope) thats still 43g/m
bottom line I bought the rope expecting it to be < 2500 and it's
significantly heavier (>10% than that)
