This couloir may actually be a good alternative for those wanting to avoid the crevassed glacier parts - as it was the case for me when I was there solo at the end of Aug. 2008. Of course if it is possible or not depends strongly on the actual conditions, but I found it quite feasible even at that late date of the year - see the pic I attached to this page (actually I didn't make it to the Fuorcla because I was very slow and would have had to redescend only in the afternoon, furthermore from the vantage point where I returned - the beginning of the narrow section - the last 10 meters or so appeared nearly vertical, and I was not equipped for that). But I'm sure that many times a year conditions are favorable to go the couloir, if one is strong enough to pass it off the reel.
Another point is that I guess it is also possible to go from Plan Mezdi directly over scree slopes to Fuorcla dal Cunfin, thus avoiding the mentioned crevasses of La Cudera glacier (see this pic).
