In reply to john alcock:
I think you have just about covered it there John, only a couple of things to add.
I thought the Cassin on the Piccolissima was easier than the Yellow Edge, and shorter too. Of course we did it when aid was not frowned on so much so may have pulled on a few more pegs whereas the Yellow edge only had one pitch where you used about four pegs, on the arete.
If you find you are having difficulties on The Comici and the weather is closing in PULL ON THE PEGS. The top section is a drain and you will have difficulty finishing it in a cold wet stonefall ridden situation.
There are other routes worth doing, the left edge of the Grande is a great V route with incredible exposure in relatively safe positions.
Second the going up late at night to avoid the tolls.
We camped outside the hut below the picollissima, you can get a meal there, or could at the time.
