Petzl's workhorse ice screws seem to manage a balance of weight and durability superbly. The steel tube allows you to take these on all your favorite ice climbs, whether that be waterfall ice in Bozeman or cragging on the Coleman, and you can be sure they're ready to take a fall every time without concern. These will end up on your rack time and time again as the trusty go-to when sending vertical ice. Weight is saved with an aluminum hanger that remains large enough to take multiple carabiners for managing belays, and the color-coordinated cranks not only allow smooth placements into the ice when you're at the "end of your rope" but allow quick identification of screw length when every second counts. Every ice rack should include a line of Petzl's Laser Speed screws somewhere in the mix.
