In reply to andybrown114: For ice and mixed I've been through Stubai (don't even remember name), 4 Generations of Rambos, Cyborgs (frame broke), Darts, Simond Monoceros (it can't get more bouncy), G20's, Raveltik Spider only to come back to the current Rambo 4:
Yes there are some annoyances (Antibott disintegrating and grivel website is dysfunctional) but they're unmatched in terms of stiffness, penetration, balance and of course the material they use which is easily sharpened, holds well but is soft enough to stick on rock.
Rambos could be lighter, but I wouldn't trade a single gram for less stiffness - even when using pebax boots.
Of course I also use semi-rigid crampons, but not for higher grade climbing anymore, really.
Btw., I have very similar experiences with tools: I have used Nomics, 2 last generations of Quarks, Fusion, Cobra, Viper with different picks/mods etc.
But nothing even comes close to Grivels X Monster: they stick at first strike, release without effort, are extremely reliable (I've several times broken one of the "important" plastics on other tools), fit in frozen cracks and between columns, their picks are unmatched in longevity and you can buy 4 tools for the same you get 2 from other vendors.
The current version also allows the attachment of full size carabiners at the bottom.
