We too at the end of July hiked-climbed the described ferrata in the same direction starting from Biacesa. Definitely ferrata Susatti is a special experience worth a visit.
The ferrata is very well secured, not too hard, but more caution is needed on the paths which are
very scenic yet precipitous. After the descent ferrata Mario Foletti which is in the same range as Susatti we descended to bivak Arcioni.
In the bivak there were just older locals and we chatted a bit. We drank coffee and beer
(two Turkish coffees + a little beer=4€

. From the bivak right after the bend we came to the little church and from there continued to the top of Cime Rocce. The path goes through tunnels from the 1st World War. First we went to the top, then across the top to the other side and through the longer tunnel under the top to the junction where we had turned up before.
Everything is nicely marked and secured. Super trip.
