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
