Hi Chrisps,
good info there as you are right - it's quite hard to find out about these routes! We were also there in Italy and did a short hit on the Via Delle Bochette.
We only had 2 days in the area (also spent some time in the Sella area - beautiful too) and did the following: Day 1 - Park at Refugio Vallisinella and take the Ferratas 327 and 358 to refugio Pedrotti - quite a long day out but amazing and varied. Ferratas and Glaciers. Stunning views around the Cima Tosa).
After a night at the Pedrotti hut (very nice) did the central section of the Bochette (305). This part has some of the classic ledges that you see on postcards/guidebooks etc. We took this to the Alimonta hut for a spot of lunch and then back to Vallisinella that afternoon.
Rather than axes we took crampons and walking poles. But you're right, some form of security on the snow/ice is very useful for the areas where the ferrata cable was totally buried. Some groups also had a short rope.
If anyones interested in the views I've posted a couple of pics on my gallery. And regarding the huts, definitely book. We called a couple that were totally booked. Enjoy!
