I am looking to step up my Climbing/Mountaineering. To some Ice and snow, I am wondering how should a Ice Axe fit? I am 6'3" and I am thinking, like a 70cm axe would fit. Am I missing anything? What should I be looking for in a Axe? Any help here would be great any suggestion on other gear(Crampons,etc) would help also. I just got a Pair of Scarpa Inverno's and I am looking for some good Crampons that will be good to walk Glaciers and Climb vert. Thanks
