More weight equals greater durability. The Imlay Canyonero 9.2mm excels when durability, value and robustness are priorities in your rappelling rope. Great for Class C (flowing water) canyons where the water flow beats your static rope against the rock. Provides a lot of rope to hold onto, both for less-skilled canyoneers and for the more-gravity-tugged-upon among us.
 
When comparing to other static rope, look at the weight per 100 feet, or the grams per meter. Many static ropes claim a larger diameter, but contain considerably less material, resulting from a very soft weave that holds up to abuse poorly. The Canyonero rope is tightly woven to resist cutting, plus uses a somewhat sheath-heavy design (52%/48%) to increase toughness and increase value.
