When choosing ropes, you have the option between single, half, twin, and static. Here is the rundown of each kind:
Single ropes are good for sport climbing, trad climbing, and big walls. This type of rope is called single, because it has been created to be used by itself (not with another rope). A large majority of climbers tend to use this kind of rope. To recognize a single rope, you will see a one on each end of it.
Half ropes tend to be utilized for mountaineering and ice climbing, as well as trad climbing on multi-pitch rock situations. Half ropes are used with another rope. The proper use of the half rope means that there will be a reduction in rope drag. This is useful for wandering routes.
Twin ropes are best for non-wandering multi-pitch routes and mountaineering and ice climbing. Twin ropes are used with another rope. When repelling, tie the two ropes together, and this will allow you to go further than a single rope would. These ropes tend to need a skilled climber who knows how to use them.
Static ropes are great for rescue climbs and caving. They can also be used for climbing fixed lines, hauling loads and ascenders. These ropes can be used in situations when you don’t want the rope to stretch. For example, if you are hauling a load up, or if you are lowering another climber, you would want a rope that doesn’t stretch, so this would be a good option.
