In reply to mcawle:
It's rare that anyone attempts anything other than guided 8000m normal routes in the area anymore. Porter costs along with all the other guff make it quite an expensive destination for a small independent team trying something new.
A team of two attempted the west(sw) ridge on K2 a couple of years ago so they would have gone near it but I think they acclimatised on their route, not Angelus. It's too far for most K2 aspirants to go and try easily, even if they were interested, or able.
I'd say that since the Russian K2 west face climb in 2006 the only climbers to the area have been two teams of two doings recces for Praqpa Ri from the north side, but as is typical for the area, found negotiating the moraines and icefalls of the nearby glaciers to be slow, hard and dangerous work without support, on top of the usual weather issues.
