I finally exchanged my old sturdy Black Diamond X-15 for a pair of these in january. Been using em several times since then, and I must say they are really good. Lightweight and cool looking. Swing nicely and penetrates ice like a porn star ;) I use em with a pair of Grivel spring leash w/ screw lock, great setup!
