The Metolius Monster is a 8.9mm dynamic climbing rope that is certified as a single, twin, or half rope, includes a dry treated sheath and core and a bright orange thread to aid in finding the halfway point.
The Beal Joker 9.1 Unicore is a specialized skinny rope for alpine routes and hard sport sends that performs like a much thicker rope. Due to high 8% static stretch, it is not for top-roping or serious hang-dogging.
The Edelrid Boa is a value-priced 9.8mm rope that is great for new climbers looking for a lightweight rope with good handling and durability. The Boa lacks some of the extra features of other ropes but proved to be reasonably durable.
