Generally speaking: "EN 1891: 1998, Personal protective equipment for the prevention of falls from a height ␣ Low stretch kernmantel ropes"; is semi static, less than 5% stretch with a fatty hanging on it and able to absorb a fall factor of 0.333 , "EN 892, Mountaineering equipment ␣ Dynamic mountaineering ropes ␣ Safety requirements and test methods" is dynamic with 12%+, and generally less than 20%, stretch and is rated in the number of falls it can take (it should be remembered that a fall on a wet rope voids the number of falls and the rope should be scrapped. If anyone is interested in the behavior of wet polymide polymers when subject to dynamic loading look it up on line ) Very little rope cord tape-sling sold in the EU is completely static. Climbing accessory cord is dynamic, or should be but once one goes below 5 or 6mm it's not necessarily so as it isn't used for threading nuts etc and doesn't comply with EN 892. There is semi static cord sold for use with activities such as caving and SRT. It should be noted that semi static and dynamic ropes are essentially the same, ok manufacture has moved on a pace but generally, a semi static rope is pre stretched, a dynamic rope not. Stretch any dynamic rope/cord enough, repeated loading, and it'll take on the properties of semi static. Thinner the material quicker one can pull the stretch out of it. Tape sling is semi static, the old white with a black line tape was/is static and should only be used for SRT or other static loading situations, abseiling hauling anchorage, rather than climbing. Enough of that, I voted other. Get a ball of string or a roll of polyester twine, costs a fraction of the price of the fancy eye candy, does the same job and one can cut it as required without fear or favor. Laid 5 or 6mm polyprop rope is great. It can be cut and divided into three thinner cords, it can be spliced, traditional knots work well; sheet bend bowline reef knot etc, and it's very light; a 50 meter hank weighs next to nothing in the greater scheme of things, it's very strong and can be split to yield 150m of cordage. Then there's bailer twine If one is after reliability and strength buy stronger string, if it's for supporting body weight where it matters, personal security from falls from height, buy a proper rated rope(s) use it accordingly and look after it.
