I really love these ice axe, both with hammer, they are very light and the pick split the ice very easily!
You can use Petzl massalot it the head is too light for you.
But Kailas only have one pick to fit these ice axes, really good for ice (I dont know for mix) but it could be nice for some person to use differect picks.
They look like the quark but petzl pick don't fit on it.
