The 11,7mm rope Argiope Blue is very comfortable to use. When used with the SpiderJack or ZigZag, there is no need to pull the whole rope through the device. The splice is very slim, so it fits through the opening. The rope is very smooth and doesn’t stiffen. When in use for quite some time, the rope’s diameter won’t increase. The Argiope Blue slides very smooth through friction savers and pulleys and doesn’t jam in crotches.
