Pics of Manhattan remind me of Rama Couloir at La Grave:
Your Manhattan pic does not rotate when clicked upon. I recommend reloading a rated copy.
Sombrero pic makes it clear you have to bail skier's right after the top pitch to avoid being sucked onto the half bare gully which forces you down to Urano. FYI here's the view down that sector from 2005, when Las Lenas had the coverage we would like to see more often:
With good coverage it was also possible to ski 2,500 - 3,000 feet down the Paraiso drainage and cut back to Urano by gravity traverse.
The Marte pic looks very similar to last year. If anything Errare Humane looks a bit wider than when I skied it then. El Collar looks better too.
Entre Rios looks awesome. Unfortunately if it takes Staley 2+ hours to hike up there, that probably means it's beyond me.
The Kirkwood guy who ran Las Lenas snow safety in 2009 thought Las Lenas control program was more extensive than he had seen in North America. Before a predicted storm they would put some patrollers in a hut up top with 10 days of provisions so they could dig out the top of Marte and control from the top down. Plus he mentioned all those Gasex installations. Nonetheless I endorse the recommendation to carry avy gear. One should never assume Las Lenas has all its bases covered.
