Hyalite Canyon local Todd Preston tested out the new Black Diamond Ultralight Express screws on some of Montana’s classic ice climbs. He concluded, “For…pursuits where weight savings can be critical, the Ultralights are clearly the new gold standard and I would rate them 5 stars. However, several days of climbing frozen waterfalls using both Ultralights and traditional Express screws revealed some design limitations….” Four stars.
Todd Preston is a geologist for the US Geological Survey who has been ice climbing for 20 years. He tested the Black Diamond Reactor ice tools and concluded that the Reactors are ideal for steep ice and cragging, awarding them a solid four stars.
