what point are you trying to make

[bob]

Personally i think NPTC training bears no relation to actual working experience and the hole Loler stuff is aimed at the blue polypropelene brigade. I've just had two 14mm ropes failed due to excessive wear (from my arb supplier whole sells rope!) disagreed with the result and used them all day knocking out a big syccy (although it was 90% top roped i admit). No worries and they're probs more 'worn' than the day before now. The strength of MarlowBraid is in the core not the outer so as long as the outer is intact and healthy and your're not pushing whats sensible i think experience counts for more than a piece of paper. Regarding angles etc is important but again the heavy stuff is often rigged off the stem so angle is no worry.

whats the point in sending your stuff to be lolered if your then going to disregard there points and petes right maybe you should think about independant if you think that they are failing stuff for sales although i would doubt that and as for the strength been in the core i suggest you investigate further and maybe tell us how you have used the rope ie pulley or natural crotch

It is unique among double braided ropes if this is the case.

 

I was under the impression marlow braid wasn't a double braid, after pulling it apart i've found it to be a 3 strand core and a braided cover. marlow themselves state it being a core dependant rope.

If you are concerned about a possible conflict of interests then why aren't you using an independent loler inspector?

 

I will be next time peter, just lost my trust he did.

Agreed. My ex yacht rigger boss has 20 years exp in ropes and splicing so i trust him totally on rope advice. He's got forearms like popeye which is a good sign!

Natural crotch rigged. Outer cover not at all frayed just a bit used and a 5 tonne BS when new. I'm just saying really that with a 10:1 safety margin that gives 500kg of SWL I think which is a reasonably large piece of wood by most standards when top roped. What did people do before loler anyway?

[Peter]

Yes, quite right it isnt double braid. 3 strand core 16 plait cover. My mistake.

 

BTW, core dependent ropes and doublebraids are completely unsuitable for natural crotch rigging.

have you tried splicing MB , Spectra and wire to rope. you'll need spinach in your diet if you do it daily
