Heading to Denali in May. (West Buttress) Had always planned to use my BD Sabretooths. Now, looking at ways to lighten my pack, I learn about the Petzl Irvis Hybrid, so I pick up a pair to try.
Half the weight. Definitely not as "burly" or aggressive, but even on blue ice, I would think that the steel front half would offer enough purchase. I've used BD Contact Strap crampons on blue ice before without any noticeable issues.
Anyone care to opine? Excitableboy?
