In reply to Blizzard:
Went in March 1993 , on the first ever Khumbu climber HK trip , it was our first peak ( mistake ! ) we bivvied at 18500 feet & had 8 inches of snow overnight , we all failed within 200 yards of the bivvy site due to lack of acclimatisation , heavy snow , general pissedoffness
We went on to climb Pokalde 5806m , Kong Ma Tse 5820m & got to top of Lobuje Far East summit 6000m , actual proper top at 6119m is a lot more technical than AD- route we did ( think first climbed by Mark Twight & Alison Hargreaves )
There was no glacier crossing before the summit ridge so you could probably solo it , but if you are not acclimatised do something else first to get a better chance of getting up.
Have fun , cheers Sean
