Only been to the Wildspitze the end of the routes I've seen. It's popular, quite popular, because it's the tallest in Tirol (now, pre 1918 was the Ortler - if it's been a really good snow year in the south check out the tours, pictures from the ski area) The other reason is the Wildspitze is easy to reach from Pitztal ski area (~2.5 hrs by memory) Cool area, can dig up some pics. Nice peaks, steep skiing to be done with the right snow, nice touring
If you head to Switzerland check out this planner - add a hut and it'll give you info:
