So personally I prefer a longer axe for easy alpine routes and winter walking. Mine is 63 cm, I'm 6ft tall.
However you are missing something IMO. My axe is long enough for to make stuff like the descent down the ridge from the aiguille du midi easier than a tech axe as well as being long enough to help as a pole on any slope steep enough to need it, generally the extra length is handy for these two cases, the first as it increases safety on dodgey terrain that isn't too steep (with perhaps a little stooping over) and as a pole on not too steep terrain. Once the slope is a bit steeper the extra length makes little difference going up or down.
When going down steep slopes you will either face in to the slope and use dagger technique or go down sideways with the axe in your up hill hand, in both cases the longer axe doesn't help really, if anything slightly the opposite. Once you can walk down the hill close to straight on, an axe would have to be very long to increase safety. Normally you are ready to arrest a slide but otherwise walking normally.
