In my experience Beals have always performed well -light and handle well - but not that durable, maybe best for snow and ice.
I had a pair of Edelweiss doubles, not the lightest in the world. But hell, those things survived a trip to Alaska, a couple ice climbing trips to Canada, tons of alpine routes in the Cascades, and the NE Ridge of Mt. Alberta. Finally retired them b/c I figured I should, not b/c they were damaged at all.
I currently have some Mammut doubles and a 9.7. I love the way they handle, but we'll see how durable.
