In reply to MikeCH:
Sentiero Roma *is* technical (read: Crampons, Piolet), esp. in June/July.
The Austrian Routes mentioned have the advantage, that you often can double the stages, easily escape to the valley from every hut etc.
There are also some more circuits of this type like Verwallrunde, Silvretta- or Lechquellrunde.
I wourld admit that scenery e.g. on the TMB is more spectacular, but as said this is quite crowded in July/August (= peak season).
