In reply to thelostjockey:
A group of us did both the Zillertal in 2014 and Stubai 2011 treks from Allan's books.
We took ropes etc on the Stubai as we were doing mountains off-route but didn't need anything for the actual trek.
We did both late August/early September and hit more snow on the later stages of the Zillertal.
However both were excellent and we only needed normal gear and poles.
On balance, I slightly preferred the Stubai but very little between them.
