I just bought a 50cm Venom hammer as a second tool to my 65cm Raven for north Cascades ski mountaineering and climbing. I'm shorter than you but my reasoning is that I'll be skinning with poles on anything under ~45 degrees and if it gets to the point that I want an axe it's to plunge up to the pick on steep faces. I don't need anything approaching cane length for that. When I have some more money I'll replace my Raven with a Venom adze.
