In reply to kenhansard: I did one of those routes and tried another, what I found was:
1) Via Classica - crapper rock than the guide suggests imo. Only one hard move on that V- crux pitch but overall climbing felt hard for the grade on most pitches, especially where the rock was crappy. Massive pain with a rucksack on a number of pitches. I squeezed behind the pinnacle as soon as I saw light through, this was too low down because I had to take everything off (helmet, gear, rucksack, etc.) and rage like a banshee to wriggle through and had no abseil on the far side. After the pinnacle, make sure to go quite far right in the 2nd pitch in the big corner to get out onto the second terrace. The hut warden, beer and food were not in situ when I reached the top!! (but there is matresses, beds and blankets for 3 in a room round the back of the hut on the summit if you finish very late (no water though)). There was some stone and icefall from melting snow/ice. The toilet at the top is just a hole over the face, so think twice about drinking the water running down the face!
Use the bivouacco on the Ombretta pass the night before you climb, it has blankets and matresses and is very close to the start of the route. Route took me 6 hours on solo. Decent is long but obvious and easy.
2) Vinatzer/Messner - A lot of pitches felt hard for the grade. Generally you can run any 2 pitches together with 60m half ropes, I found this useful to keep speed up. Route finding was fine till the bit terrace, after that we never did really feel we were back on the line. Tried to force a way out of the top of the face but it completely blanked out when I would guess we were level with the shattered yellow crack. We abseiled to the terrace, spent a vilely cold night snuggled under an overhang there and then spent many hours abseiling and backclimbing traverses the next day (No water or food or energy to try the top half again). A chap I met out there this year said that there are a couple of sleeping bags stashed in a cave near the Vinatzer/Messner line on the big terrace for people to use in an emergency... I wouldn't rely on them though
Not done Don Quixote but it sounds nice. Worth bearing in mind that two of these routes have a crux pitch right at the very end so you really need to be confident that after 20+ pitches, you can still climb E1/2.
There is bound to be a guide in german out there somewhere with more Marmolada routes. You can go a long way with a topo and translations for common climbing terminology. Or in Italian for that matter.
As the other guy said, the Marmolada isn't known for its easier classic routes. It is known for its modern testpieces.
