In reply to 0153453:
Have spent ten years on via ferrata holidays. Called klettersteigs in german speaking countries (Germany and Austria). Can thoroughly recommend the Zugspitze near to Garmisch and the Innsbrucker in Austria (above Innsbruck) but there are many more from easy to very difficult depending what you want, almost too many to choose from.
Only been to the Dolomites once in 2013 but going back again this summer. We did Brigata Tridentina to name one which was awesome but is very popular so expect long queues if you do it in August. Also well worth a visit to see Tre Cime di Laverado and the via ferratas in that area. Again the choice is endless depending which bit of the Dolomites you go to. You wont be disappointed.
As you probably know Cicerone do two good volumes on Via Ferratas in the Dolomites and Rockfax has recently produced a guide (mostly sport routes with some trad but a good helping of Via Ferrata too). There are many more available in german language and italian and no doubt french. The later guides cover more than the English guides and are not to hard to understand even if you don't speak the language.
Just one more point those Via Ferratas in the South Tyrol have german and italian names which can confuse until you get used to it.
Have a great trip when you go.
