I decided do this trek with Third Rock Adventures and they were very helpful in helping organizing the trek in general. Naba coordinated a porter guide for my solo trip and also everything required for this trip. He also helped me get a seat on a plane back to KTM, thank you again! My guide Bir Bahadur was very knowledgeable about the trail and did speak some english. He helped arrange accommodation in tea houses and was regularly asking other sherpas for trail updates along the way. I would just recommend anyone who does this trek in general to bring lots of snacks - past Shipton La expect a diet of rice and potatoes. I got really hungry on the way down. The trail conditions were unexpectedly snowy (several meters of snow and warm T up and down Shipton La). Nepalese people have no training/awareness of avalanche risks. Use your best judgement and speak up if you feel uncomfortable. Actually I loved the adventure and remote experiences of this trip. Thanks to all.
