Just an fyi: Bought a 66cm Evo (slider, not the long leash), and used it last weekend on the north side of Mt. Shasta.
Did some group-arrest practice with a rope team and didn't notice any problems. Plunged the pick into glacier ice during crevasse rescue practice, and was pretty well impressed. The steel spike worked well on summit day, where we encountered patches of blue ice. In areas of talus / rock I had to use the axe for balance. Pounded a picket in with the spine. Dug out a buried deadman with the adze, where it was good to have a solid 'shovel'. Good solid tool.
The guides were using BD Raven's, so can't really say I was pushing the limits of the tool, except maybe for the glacier 'ice climbing' (really just hauling myself out of the crevasse after prusiking up). It was kinda cool to whack that pick in and lever myself up while gripping the adze.
Afterwards, had to sharpen up the spike a bit because of all the clanking on rock, and some of the fancy paint job was pretty well smudged. Small spots of light rust were evident on the head, but that seems normal for Grivel chromoly steel.
